Wood Restoration in Portsmouth

Sashes, doors, porches and millwork repaired rather than replaced — in houses that were here long before any of us.

Why The Old Ones Are Worth Keeping

A sash made in 1890 is old-growth timber — tight-ringed, dense, and more rot-resistant than anything milled today. It was also built to be taken apart: every component in it can be replaced individually, which is precisely what a modern sealed unit cannot offer when it fails in year fifteen.

Repair typically costs well under half of replacement, keeps glass that has been in the opening for a century, and in a historic district usually avoids a review process entirely. Add weatherstripping and a storm and the performance gap most salespeople quote largely closes.

How A Repair Works

Four Steps To A Repair You Cannot Find

This is the method behind every item on the list above, from a threshold to a column base.

01

Find the sound wood

Rot stops somewhere. We probe until we reach timber that is still solid, because a repair let into soft wood fails in the same place within two years.

02

Cut a clean pocket

The damage is cut out to a square-edged pocket rather than chased along the grain. It takes longer and it is the difference between a repair and a patch.

03

Let in matching timber

A Dutchman of the same species, with the grain running the same way, glued and pinned. The same wood moves the same way through a Seacoast winter.

04

Shape, prime and blend

Worked back to the original profile, primed on all faces including the end grain, and blended into the surrounding paint. Once it is painted, nobody finds it.

What Comes With It

Four Things In Every Quote

Lead-safe working

Every Seacoast house we touch predates 1978. We are an EPA certified firm — containment, work practice and cleanup are in the price, not an option.

Photographs of the damage

Before we close anything up. You get the pictures, which matters when you sell the house or argue with an insurer.

An honest replace recommendation

Sometimes a component is genuinely gone. We will say so, price the replacement, and make it to match rather than pretend a repair will hold.

A first-winter check

We come back after the first season on sash work and adjust anything that has settled. No charge, and we book it when we finish.

The Shop

Four People On Islington Street

01

Small on purpose

Four joiners. Restoration cannot be rushed and cannot be staffed up in a hurry, so we keep the book short.

02

Bench work, not site work

Sashes and doors come back to the shop where they can be taken apart properly and glazed under cover.

03

We keep the profiles

Cutters and drawings from past jobs are kept, so a neighbor with the same house can have matching trim years later.

04

We say no

Whole-house renovation, plaster conservation, slate. We name the Seacoast specialist rather than stretch to it.

Three window companies told us the sashes were beyond saving. Marchbank repaired fourteen of the sixteen, kept the old glass, and the two they replaced they made to match. The house still looks like itself.
Peter V.
Our porch columns had gone soft at the base, which everyone told us meant new columns. They cut out the rot, let in new wood and painted it. You cannot find the repair and it cost a fraction.

They came back after the first winter to check the sashes and adjust a cord, unasked and at no charge. That is not a thing that happens.
Second Opinions

Four Things People Are Told That Are Usually Wrong

“These sashes are beyond saving”

Said about windows that have already lasted a century. Unless the stiles have gone right through, the components come apart and get replaced one at a time.

“The whole column has to go”

Rot in a column almost always starts at the base where water sits. The upper nine-tenths is usually sound old-growth timber worth keeping.

“Nobody makes that profile anymore”

True, and beside the point. We take a cut-off, grind a cutter to it and run new stock to match in the same species.

“Repair costs more than replacement”

Occasionally true on a badly gone element and we will tell you when it is. On sashes, porches and thresholds it very rarely is.

Questions

Before You Get In Touch

Is repairing sashes really cheaper than replacing?

In our experience, typically well under half — and that is before you count the fact that repair usually avoids a historic-district review. It also keeps glass that has been in the opening for a century, which cannot be bought back once it is gone.

What about draughts and heat loss?

A repaired sash with proper weatherstripping and a storm window performs far closer to a replacement unit than most salespeople suggest. It is also repairable in year twenty, which a failed sealed unit is not.

Can you match glass?

We keep salvaged period glass and use it where a pane is genuinely broken. It will not be identical — old glass never is, which is the point — but it will sit far better in the opening than a modern flat sheet.

What is a Dutchman repair?

Cutting the rot out to a clean square pocket and letting in a new piece of the same species, grain running the same way, then working it back to the original profile. On painted work it is invisible once finished, and it is why a column base costs a fraction of a new column.

How do you decide repair versus replace?

We probe for sound wood. If enough of the original remains to hold a repair and carry the load, we repair. If it does not, we say so plainly and make the replacement to match. We would rather lose the sale than sell you a repair that fails.

What does lead-safe certified mean for me?

Every Seacoast house we work on predates 1978, so it is assumed to have lead paint. Being an EPA certified firm governs how we contain, work and clean. It is in the price rather than added later, and it is not something a contractor can offer to skip.

How far out are you booked?

Usually six to twelve weeks, and sash work is seasonal — we prefer to have windows out in the warmer months. The real date goes on the quote and we tell you before it if anything threatens it.
