Deck repair

Deck repair in Michigan is a race against the calendar. Fasteners, sealers and concrete all need temperatures that stop cooperating sometime in November, and a deck that goes into winter with a loose railing or a soft board comes out of it worse. Wright’s Repairs handles boards, railings, stairs and skirting as a visit, on a written price, without rebuilding a structure that is still sound.

What a Michigan winter does to a wooden deck

Seventy freeze and thaw cycles a year is brutal on anything horizontal and outdoors. Water sits in the gap between boards, expands as it freezes, and works the fasteners loose a fraction at a time. Salt tracked from a driveway pits the hardware. By the fifth or sixth winter the deck has not failed, but every connection in it has moved.

Where decks fail first

Board ends, because end grain drinks water. The stair stringers, which sit closest to the ground and stay wet longest. The ledger where the deck meets the house, which is the connection that matters most and the one nobody looks at. Posts at grade, especially any set directly into soil rather than on a footing.

When repair stops being honest

Framing that is soft, posts that move when you push the rail, or a ledger that was never flashed and has been wetting the rim joist for a decade. Replacing boards on top of that is putting a new surface on a structure that is going to have to come out anyway. At that point the answer is new deck construction rather than another season of patches.

Boards that are soft, split or cupped

Deck board replacement swaps out what has gone without touching the frame underneath. The honest caveat is color. A new pressure treated board will not match a deck that has weathered for eight years, and even composite fades, so a replacement reads as a replacement until everything has aged together. We say that before ordering rather than after installing.

Cupping is worth understanding rather than just correcting. A board that has curled into a shallow trough is holding water on its surface, which accelerates everything. Flipping it buys a season at most. Where several boards in a run have gone the same way, the cause is usually moisture from below, which means the ventilation under the deck or the grade beneath it is the actual problem.

Fasteners get replaced as a matter of course on any board work. Nails back out over years of movement and become the thing that catches a bare foot in July, and screws that have corroded through no longer hold anything even when they look fine from above.

Railings, which are a safety item rather than a detail

A railing that moves when you lean on it is the most dangerous thing on most properties, and it is also among the cheapest to put right. Deck railing repair re-anchors posts into the frame with through bolts rather than screws into end grain, which is how most of them were attached originally and why most of them are loose.

Baluster spacing is the other thing we check, because older decks were frequently built to a spacing that would not pass today, and a gap a small child can get through is worth closing whether or not anybody is inspecting. On a deck being prepared for sale it will come up in the report, which is why it lands on nearly every pre listing repairs list.

The indoor version of the same work, stair rails and guards inside the house, sits with stair railing installation on the carpentry side.

Stairs, stringers and the step that flexes

Deck stairs take the most load per square foot and sit in the wettest position on the whole structure. Deck stair repair covers treads that have split, stringers that have gone soft at the bottom, and the connection at the top where the stair meets the deck frame, which is where failures actually happen.

The base of a stair matters more than the top. A stringer sitting on soil rather than a pad wicks moisture continuously and will rot from the bottom up no matter how good the lumber was. Setting it on a proper pad is part of the repair, and where the pad itself has heaved or spalled, concrete repair handles that in the same visit.

What we look at on any deck stair call:

• The bottom foot of every stringer, probed rather than eyeballed
• What the stringers land on, and whether water can drain away from it
• Rise and run consistency, since an uneven step is how people fall
• The hanger or ledger at the top, which is the real load path
• Handrail graspability and height, both of which changed in newer code

Skirting, and what lives under your deck

Skirting is usually asked for on appearance grounds and delivers most of its value somewhere else. Open framing under a deck is an invitation to skunks, groundhogs and anything else looking for a dry space, and once something has moved in, removing it is somebody else’s trade and a worse afternoon.

Deck skirting installation closes the perimeter while keeping the airflow that stops the underside rotting, which is the balance most homeowner attempts miss. Sealing it tight is worse than leaving it open. Grade and drainage under there get looked at in the same visit, since standing water beneath a deck shortens its life more than anything happening on top.

Cleaning and sealing, and the order that matters

A deck that looks grey and tired is often structurally fine and simply dirty. Power washing takes off the algae film that makes a north facing deck slick in spring, though it has to be done at the right pressure, because too much lifts the soft grain and leaves a furry surface that no finish will fix.

Sequence is everything. Repairs first, then cleaning, then drying, then finish. A deck washed on Saturday and sealed on Sunday traps moisture under the coating, which is why so many sealing jobs peel within a year. The finishing side of this work sits with deck staining and maintenance.

New pressure treated lumber needs to weather before it will take a finish at all, usually a season. Putting sealer on wood that is still wet from the mill is the most common reason a new deck looks bad in year two.

The rest of the outside, in the same visit

Deck work rarely arrives alone. A crew already outside with tools and a ladder set is the cheapest time to handle a fence repair, reset address numbers and exterior hardware, or take on whatever else has accumulated on the exterior repair list since spring.

Autumn brings two more. Holiday lighting installation books solid in early November, and the work to winterize the house is the single visit with the best return of the year. In April the counterpart is the spring opening package, which is when most deck damage gets discovered.

Damage that arrives suddenly is handled differently. After a storm we board up the opening and document everything photographically before permanent work is scoped, so the adjuster sees the condition rather than the repair.

Composite, wood and knowing which you have

The two materials fail differently and repair differently, and plenty of homeowners are not certain which they own. Pressure treated wood splits, cups and rots from the end grain and the underside. Composite does none of that and instead scratches, stains, sags between joists if the spacing was wrong, and fades unevenly where furniture has sat.

Composite repair has a harder constraint: matching. Product lines change every few years and get discontinued, so a board replaced on a twelve year old composite deck may be the closest available rather than the same thing. Where the original color is gone entirely, taking boards from a less visible run and putting the new ones there is usually a better answer than a mismatched patch in the middle of the field.

Early generation composite is worth knowing about. Some products from the late nineties and early two thousands absorbed water and grew mold, and several were subject to class settlements. If that is what you have, patching it is money badly spent, and replacing the surface on a sound frame is the conversation worth having.

The ledger, and the connection worth checking yourself

The ledger is the board bolting your deck to the house, and it is the single connection where failures are serious rather than inconvenient. Decks that collapse almost always come away at the ledger, usually because it was nailed rather than bolted, or because it was never flashed and the rim joist behind it has been slowly rotting for fifteen years.

You can check part of this without tools. Look at where the deck meets the house and see whether there is flashing over the top of the ledger, or whether siding simply runs down to it. Then look for rust streaks and staining below the bolts. Either sign is worth a proper inspection before anybody spends money on the surface above it.

Where flashing was missed, the repair usually involves the wall as well as the deck, which brings in siding repair and belongs on any water damage prevention pass. This is the one item on this page where we would rather you called about it too early than too late.

Deck work we hand to somebody else

Structural rebuilds leave the repair side. New framing, new footings, a deck being enlarged or raised, or a ledger that has to be pulled and reflashed are all permitted work with engineering behind them, and they belong with the deck team rather than a service visit. The published list of work we do not take sets that boundary out in writing.

Enclosing a deck is also a project rather than a repair, whether that means a screened porch enclosure, converting to a porch, or building out a full outdoor living space. Those change the roof, the footings and usually the permit, so they get designed rather than scheduled.

How a deck repair visit actually runs

Send photographs of the whole deck from the yard, a close shot of anything failing, and one from underneath if you can get there safely. The underside picture is the most useful thing you can send, because it shows the framing, the ledger and what the posts are sitting on. We come back with a written scope and a flat price.

Most deck repairs are one visit, weather permitting, and we will move a date rather than fasten into wet lumber and have you call us in April. If what we find under the deck is worse than the photographs suggested, you hear it on site with a price, not in a change order afterward. The rest of that approach is on our page about how we work.

Clearing the deck ahead of the visit genuinely speeds things up, and if furniture, planters or a retired grill are going anyway, junk removal can run first. Bundled outdoor lists sit on the home repair packages page.

Where we work across Southeast Michigan

Crews cover Washtenaw, Wayne, Oakland, Macomb, Livingston and Monroe counties. Deck age tracks subdivision age closely. A great many decks through Canton, Novi and South Lyon went up in the late nineties, which puts them squarely in the window where the frame is fine and the surface and railings are not.

Older properties around Ann Arbor and Ypsilanti often have a deck added to a much older house, where the ledger detail is the thing worth inspecting first. Lakefront and river properties out toward Brighton and Whitmore Lake carry more exposure and more moisture, and they wear through finishes noticeably faster.

Scheduling in this category is genuinely seasonal rather than a sales line. Between roughly April and early November the work is straightforward. Outside that window fasteners, adhesives and any concrete become unreliable, and we would rather tell you to wait until spring than take money for a repair that will not hold.

Get the deck safe before the freeze

The two things worth doing before winter are the railing and the stairs, because those are the safety items and because both get worse over a season rather than staying still. Boards can usually wait until spring. A loose post at the top of a flight of stairs should not.

There is also a cheap piece of maintenance worth doing yourself while you are out there. Clear the leaves and debris out of the gaps between the boards before the first snow. That gap is a drainage channel, and packed full of wet leaves it holds water against the board ends all winter, which is precisely the condition that rots a deck from the top down.

Walk the deck and push on every railing post, then look at the bottom of the stairs. If anything moves, that is the list. An annual home check visit puts the same inspection on a schedule so it happens before something fails rather than after.
