Doors, fascias, soffits and timber frames
Exterior Woodwork Painting
Exterior woodwork should be repainted as soon as the paint starts to crack, flake or let bare wood show, because once water gets into timber it swells, the paint lifts further and rot can set in; catching it early means sanding and recoating rather than cutting out and repairing wood.
This guide covers how we approach doors, fascias, soffits, bargeboards and timber frames: what to look for, how the preparation is done and why the weather matters so much for outside work.
Signs your woodwork needs painting
Walk round the house and look at the most exposed faces first, usually those facing the prevailing weather and the lower edges of doors and frames where water sits. Look for:
- Hairline cracks in the paint along joints
- Flaking or peeling that shows bare, grey timber
- Soft spots when you press the wood with a fingertip
- Dark staining or mould on sills and bottom rails
Repairs before paint
Paint will not save timber that is already rotten. Soft areas are cut back to sound wood and filled with an exterior grade repair system, or the section is replaced where the damage goes too deep. Doing this before painting is what stops the problem appearing again a season later.
Loose putty, open joints and gaps where timber meets masonry are sealed at the same stage, because those are the routes water uses to get behind the paint.
Sanding, priming and coats
Sound but weathered paint is sanded to a smooth, keyed surface, and any loose coating is removed back to a firm edge. Bare timber is primed so the following coats bond properly and the wood is sealed against moisture.
Undercoat and top coat then follow in the system the paint maker specifies. Skipping coats saves time on the day but shortens the life of the finish, so it is one of the questions worth asking any decorator who quotes for exterior work.
Why the weather matters
Exterior paint needs dry timber, dry air and temperatures within the maker's range to cure properly. Painting onto damp wood, or just before rain or a cold night, is a common cause of early failure.
That is why outside work is usually planned for the drier months and scheduled flexibly, so we can move a day if the forecast turns. Our best time guides explain the seasons in more detail.
Choosing the right finish
Modern exterior systems include both oil based and water based options. Microporous finishes let moisture inside the timber escape while keeping rain out, which suits most softwood joinery. Hardwood doors and features sometimes suit a stain or oil instead, depending on the look you want.
Colour also plays a part. Dark colours absorb more heat in the sun, which can make timber move more, so on south facing woodwork lighter shades often last better.
Looking after woodwork between repaints
A little maintenance stretches the time between full repaints. Washing painted woodwork once or twice a year removes the dirt and algae that hold moisture against the surface, and it makes small cracks easier to spot while they are still easy to fix.
Clearing gutters and keeping plants trimmed back from walls and frames also helps, because overflowing water and damp foliage are two of the quickest ways to break down exterior paint. Touching in small chips before winter stops water finding a way in, and means the next full repaint needs less repair work beforehand.
Common questions
How do I know my exterior woodwork needs painting?
Cracking, flaking or peeling paint, bare grey timber, soft spots or dark staining on sills all show it is time.
Can you paint over rotten wood?
No. Rotten areas are cut back and repaired or replaced first, otherwise the problem returns under the new paint.
What time of year is best for exterior painting?
Usually the drier months, when timber and air are dry and temperatures suit the paint. We plan around the forecast.
Do you paint fascias and soffits?
Yes, along with doors, bargeboards, frames and other exterior timber, as part of our exterior painting work.

Yes. Every job starts with a free written quote after a visit.
