Dominguez Construction Siding operates a free referral service linking Portola Valley homeowners, property owners, and businesses with independent local siding pros. We are not the contractor, and we say so plainly. Our job is to pick up at any hour, sort out what kind of siding problem you are dealing with, and send you to a licensed, insured independent pro who does that specific work in Portola Valley.
That matters more than you might think. A vinyl repair specialist is not always the right call for a cedar clapboard house, and a crew that re-sides new subdivisions may not want a two-panel storm patch. Getting the right pro on the job is how you skip the three-day callback and the estimate that overlooks half the damage.
Homes in Portola Valley cover a wide range: older houses with original wood or aluminum siding, mid-century ranches that were wrapped in vinyl decades ago, and newer builds in fiber cement or engineered lap. Each one fails in its own way, and each needs a contractor who knows the material.
For homes inside an HOA, the contractor can help you assemble the color and profile details your board will want to review. If the project calls for a permit from the local building department, a reputable pro will say so early and take care of the filing.
Expect a few short questions when you call: what your siding is made of, where the damage sits, whether water is coming in, and how quickly you need help. That two-minute conversation is what lets us send the right independent pro to your Portola Valley address instead of whoever happens to answer first.
Every Kind of Siding Job, One Phone Call
Nearly every siding call we route lands in one of six categories. Below is what each type of job really involves, what a careful contractor looks at, and what to expect before you see a price.
Emergency and Storm Damage Siding Response
When high wind strips panels off a gable end or a limb comes through an exterior wall, time matters. House wrap was never meant to be the finished surface, and raw OSB sheathing soaks up water fast once it is exposed. That is the reason storm calls move to the front of the line.
A first emergency visit is about keeping water out, not pitching a whole new exterior. A good contractor will fasten down loose courses, patch or replace torn wrap, sheet over open areas, and photograph each side of the house before work starts. Those photos matter later if you file an insurance claim.
When a limb is still resting against the house or the meter base took a hit, keep your distance and call the power company first. Siding contractors work around service masts and meters, but they do not touch live electrical equipment. Once everything is safe, most contractors can tarp, sheet, and button up the wall that same day.
- Short-term weather protection over torn wrap and open sheathing
- Re-securing vinyl panels that unlocked from the course below
- Hail impact mapping on vinyl, aluminum, and painted fiber cement
- Dated photo documentation you can hand to your adjuster
Siding Repair for Cracks, Rot, Warping, and Loose Panels
Plenty of siding problems never call for a full tear-off. A cracked vinyl panel from a stray baseball, a warped section next to the grill, or a single soft clapboard under a window can usually be fixed in a few hours. The skill is in the details: unlocking vinyl with a zip tool without kinking the courses above, sourcing a profile that actually matches, and finding out why the damage happened in the first place.
Rot is the problem that catches most owners off guard. Soft wood at the bottom of a window usually traces back to missing head flashing or a failed sill pan, not the siding itself. A contractor worth your time will probe the sheathing, check it with a moisture meter, and correct the water path before the wall gets closed.
Matching is the other half of a good repair. Vinyl lightens with sun exposure, so a fresh panel from the identical line can still stand out on a sunny wall. Seasoned repair contractors measure the reveal, profile, and butt height, carry a sample to the supplier, and if nothing matches, borrow a panel from a hidden spot behind a deck or bush.
- Single-panel swaps and partial-wall repairs
- Rotted clapboard, trim, and sheathing replacement
- Melted or heat-warped vinyl near grills and reflective windows
- Woodpecker holes, impact cracks, and pest entry points
Residential Siding Installation and Full Replacement
Re-siding a house is a major decision, and installation quality matters more than whatever logo is on the carton. Siding warranties hinge on the manufacturer's installation instructions, which means shortcuts can cancel your coverage before the dumpster leaves.
On a correct replacement, the old siding is stripped to the sheathing so the wall can be checked. Damaged sheathing is cut out and replaced, the weather barrier is lapped shingle-fashion with taped seams, openings are flashed in sequence, and a level starter line is struck before course one. Corners, J-channel, and trim are set plumb, so courses line up with window heads instead of drifting.
Find out how the old cladding comes off and where it goes. On homes built before 1978, any painted wood or trim that gets disturbed may contain lead, and contractors who work on those houses should follow lead-safe work practices with plastic sheeting, HEPA cleanup, and proper disposal. If your home is that age and the bid is silent on it, raise the question.
- Tear-off, disposal, and sheathing repair
- House wrap or rainscreen installation behind new cladding
- Insulated vinyl and foam-board upgrades for better efficiency
- Profile and color guidance, from Dutch lap to board-and-batten
Siding for Commercial, Rental, and Multi-Family Buildings
Rental properties, storefronts, small offices, and HOA communities run on different rules than a single-family house. Work has to happen around tenants and customers, scaffolding and lifts need to be staged safely, and the finished look has to match across dozens of units. Property managers usually need a written scope, a phased schedule, and proof of liability and workers comp coverage before anyone sets up.
Commercial callers frequently need someone who can handle one storm-hit building now and a phased re-side of the whole property later. We connect them with independent commercial-capable pros who carry the equipment and insurance for that scale.
Commercial wall assemblies often carry extra requirements, from fire-rated sheathing on certain building types to specific fastener schedules in high-wind zones. A contractor set up for commercial work will review the plans or the current wall build-up before pricing it, instead of treating it like a home.
- HOA and multi-family phased re-siding
- Storefront and office building cladding repair
- Fire-rated and code-specific assemblies where required
- Occupant-friendly scheduling and end-of-day cleanup
Fiber Cement, Natural Wood, and Engineered Siding
Vinyl is the most common call, but plenty of homes are clad in something heavier. Fiber cement is heavy, resists fire, and holds paint nicely, but it must be cut with dust controls because of its silica content and installed with the right clearances above roofs and soil. Each butt joint gets a flashing strip behind it, and nails are set flush rather than sunk.
Cedar and other real wood siding can last decades when boards are back-primed, nailed with stainless or hot-dipped galvanized fasteners, and hung over a drainage space. Cheap nails cause the black streaking you see on neglected wood walls. Engineered wood lap lands in the middle on weight and price, provided cut ends are sealed and the bottom row stays clear of mulch and dirt.
Metal siding is coming back on modern farmhouse and contemporary designs, and older homes still carry plenty of original aluminum. Dented aluminum can sometimes be swapped panel by panel if the profile is still available, and steel lap or board-and-batten is sold in factory finishes that hold color for a long time. Either way, the pro should use fasteners compatible with the metal to avoid corrosion.
- Fiber cement lap, panel, and shake work
- Cedar clapboard, shiplap, tongue-and-groove, and shake
- Engineered wood lap and trim systems
- Aluminum and steel siding repair on older homes
Trim, Soffit, Fascia, Flashing, and Siding Inspections
The cladding is only as good as the details around it. Most wall leaks we hear about begin at a missing kick-out flashing at a roof-to-wall joint, a split caulk line at a window, or a soffit that lets driven rain behind the cladding. They cost little to fix early and plenty to fix late.
Many callers simply want a set of trained eyes on the house before buying it, before a storm season, or after one. A siding inspection usually covers fastening, clearances, flashing, caulk, signs of moisture behind the wall, and whether the material is near the end of its service life.
A thorough inspection ends with a written summary and photos, not just a verbal opinion on the driveway. That summary is useful whether you are negotiating a home purchase, planning a budget for next year, or documenting condition before a storm season.
- Kick-out flashing, drip cap, and Z-flashing installation
- Vented and solid soffit replacement and fascia wraps
- Pre-purchase, post-storm, and routine inspections
- Moisture meter and infrared scans behind suspect walls
How Siding Actually Fails, and What a Good Pro Checks
After years of routing siding calls in Portola Valley, the same few failures come up over and over. None of them are mysterious once you know where to look.
Vinyl that was nailed down hard. Vinyl moves a lot with temperature. It is supposed to hang loosely on nails centered in the nailing slots, with a small gap left at each end for expansion. Nail it tight and the panels buckle into waves on the first hot afternoon.
Missing kick-out flashing. Where a roof edge dies into a sidewall, water runs down the step flashing and needs a small diverter to throw it into the gutter. Without it, that water goes straight behind the siding, and we have seen the sheathing under those corners turn to mush within a few seasons.
Cladding sitting too low. Siding that touches soil, mulch, or a patio wicks moisture and invites insects. Manufacturers call for a clearance above grade and above roof surfaces, and fiber cement in particular is unforgiving here.
Sealant used where flashing belongs. Caulk is a backup seal, not a plan for handling water. When we hear about a leak that keeps coming back after every new bead of sealant, there is almost always a missing piece of metal underneath.
No weather barrier, or one installed backwards. House wrap has to be lapped like shingles, upper sheets over lower ones, so water running down the wall stays on the outside. Backward laps and open tears steer water right into the sheathing, and plenty of older houses have no barrier behind the cladding at all.
Nails that corrode or stain. Plain steel nails rust, stain the face of wood siding, and lose holding power over time. Wood and fiber cement need hot-dipped galvanized or stainless fasteners, and coastal homes really should be on stainless.
Green streaks do not always mean rot. Dark or green streaking on shady walls is often just mildew or algae that a soft wash with a siding-safe cleaner takes off. Rot is different: the material feels soft, sounds hollow, or crumbles when probed. A contractor can tell them apart quickly, which can save you from paying for an unnecessary repair.
A word on timing. Spring and fall are the busiest seasons for planned siding work, and storm season brings sudden spikes in emergency calls. If your project can wait, booking an estimate a few weeks ahead of those rushes usually gets you more scheduling options.
Should You Repair or Replace Your Siding?
Portola Valley homeowners ask this more than anything else, and the real answer depends on how much of the wall is involved and what caused the damage.
When a repair usually makes sense
The damage stays on one elevation or a handful of panels, the remaining siding is solid and well fastened, the sheathing is dry, and a decent match can be found. Wind blow-offs, impact cracks, heat warping, and localized rot from one missing flashing typically land in this group.
When replacement starts to win
Multiple walls are cracked, faded, or brittle, panels keep releasing because the original job was poor, soft sheathing appears in several places, or the material is too old to match. Paying for repeated repairs on a failing wall often costs more over a few years than doing it once properly.
What drives the price of a siding job
Every quote comes down to a few factors. Material is the obvious one: vinyl generally costs the least, engineered wood and fiber cement sit in the middle, and natural wood and premium metal run higher. After that comes the size and height of the walls, how many windows and corners need trim, whether old siding has to be removed and hauled off, and how much sheathing needs replacing once the wall is open.
Access matters too. A three-story wall over a sloped yard needs staging or a lift, and that time shows up in the bid. Hidden rot is the unknown, so a careful contractor will tell you up front how surprise sheathing repairs will be billed.

Warning signs worth a phone call
- Panels that are wavy, bowed, or pulling away at the bottom edge
- Cracks, holes, or chips that show house wrap or wood underneath
- Soft, spongy, or crumbling spots near windows, doors, or the foundation
- Bubbling paint or water marks on the inside face of an outside wall
- Mold, mildew, or green growth that returns quickly after cleaning
- Rust runs under nails or dark streaks on wood boards
- Gaps at corners, J-channel, or trim where daylight or insects get in
- Energy bills climbing for no obvious reason
Any single item on this list could be small. Two or three at once, particularly around windows or roof edges, usually point to water getting behind the wall. That is when to have an independent contractor take a closer look, before a small fix becomes a full wall repair.
A quick look at the main siding materials
Vinyl
The most common choice for its low cost and minimal upkeep. Thicker panels resist wind and impact better, and insulated vinyl adds a foam backer for stiffness and comfort. It needs to hang loosely so it can expand and contract.
Fiber Cement Plank
Heavy, fire-resistant, insect-proof, and great at holding paint. It calls for dust-controlled cutting, joint flashing, and careful clearances above soil and roof lines.
Natural Wood
Classic looks and a long life when maintained. Boards should be back-primed, nailed with stainless or galvanized fasteners, and refinished on a regular cycle.
Engineered Wood
Lighter than fiber cement, with wood texture at a mid-range price. Sealed cut ends and good clearance from dirt, mulch, and puddles are a must.
Notes From Portola Valley Homeowners We Connected
These are follow-up comments from callers in and around Portola Valley, shared with permission and lightly edited for length.
A thunderstorm ripped about eight feet of vinyl off the back of our house around midnight. I called expecting voicemail and got a person. The contractor was out the next morning, got everything covered before the afternoon rain, and came back two days later with matching panels.
Denise R.Portola Valley storm damage repairI thought I needed all new siding because the wall under our bathroom window was soft. The pro pulled three boards, showed me the window had no flashing at the top, and fixed that plus the rotted sheathing. Way less than I braced for.
Marcus T.Portola Valley rot and flashing repairWe re-sided our 1960s ranch. The crew stripped it to the sheathing, replaced two sheets of rotted plywood, wrapped the house, and flashed every window before hanging insulated vinyl. Our upstairs is noticeably quieter and less drafty.
Angela and Ray P.Portola Valley full siding replacementI look after a fourplex and had one wall damaged by a fallen tree. The contractor emailed proof of insurance before arriving and scheduled around my tenants. Neat, professional work.
Kevin L.Portola Valley rental property repairOur home sale hit a snag when the inspector noted loose siding along the side yard. The contractor came out two days later, refastened and swapped the damaged panels, and sent photos and an invoice I could share with the buyer.
Harold B.Portola Valley pre-sale siding repairThe barbecue warped a patch of vinyl by our patio. A small job, but no one returned my calls. Through this line I had a pro out that week who replaced the panels and told me how much clearance to give the grill.

How fast can a Siding technician arrive in Portola Valley?
It depends on the time of day and what is happening outside, but storm and active-leak calls are flagged for the fastest response available. Many emergency calls in Portola Valley see a contractor the same day or first thing the next morning. Routine repairs and replacement quotes typically get booked within a few days.
Do you provide upfront pricing?
Independent pros in our network put a written price in front of you once they have inspected the siding. Quoting blind over the phone is just guessing, and careful contractors avoid it. You will know the scope, the materials, and the total before you agree to anything.
What emergency siding services are available?
Emergency calls include wind blow-offs, tree or vehicle impacts, open sheathing, and water coming through to the interior. Step one is temporary weather protection plus photos, then a lasting repair once matching material is in hand.
Is calling your line free?
Yes, the call is free and you are never required to hire anyone. Dominguez Construction Siding works as a referral service, so the contractor you talk to quotes you directly.
Can a contractor match my existing siding?
In many cases, yes. Vinyl and fiber cement can usually be matched by measuring the reveal, profile, and grain, then taking a sample to a supplier. When a color is discontinued or faded, some pros borrow panels from a less visible wall and put new material there instead.
Will my homeowners insurance cover siding damage?
Sudden damage from wind, hail, or falling trees is commonly covered, while wear and slow rot usually are not. Your policy decides, so call your insurer. The contractor can supply photos and a written damage report for your claim.
Do I need a permit for siding work in Portola Valley?
Small repairs often do not, but full replacements frequently do, depending on local rules. A reputable contractor will check with the building department and pull the permit if it is required.
How long does a full siding replacement take?
An average single-family home usually takes a few days to about a week and a half. Sheathing repairs, complex trim, weather, and material lead times can stretch that. Ask your contractor to put the timeline in writing.
What questions should I ask a siding contractor before hiring?
Request proof of insurance, confirm any locally required license, and get a written scope that names the flashing, weather barrier, and who handles the permit. Also ask whether the install will follow the manufacturer's instructions, since that is what keeps the product warranty valid.
Can siding be repaired in cold or rainy weather?
Temporary weatherproofing can be done in almost any weather. The permanent repair depends on material, since vinyl turns brittle in hard cold and paint and sealant on fiber cement or wood need temperatures within their rated range. Your contractor will plan the timing around it.
