- Cracked internal joints between frame and plaster
Aftercare tips
To keep the joints looking good and working properly:
- Do not use solvent cleaners on the joint
- Keep drainage slots and sill grooves clear
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
How we handle window mastic in Woodside
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Typical jobs include mastic that has split away from the wall and rain getting in at the frame or under the sill, across window sills, patio & French doors and uPVC windows.
Around Woodside, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, it’s backed by our 12-month guarantee in Woodside and across Windsor and Maidenhead.

Windows and doors in Woodside
Historic houses like St Leonard's Hill (about 2.6 miles north) are a reminder that the area around Woodside has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Ascot station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Cranbourne Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface

Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door, and the area is left clean. In a small place like Woodside, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can

Why act early in Woodside
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Older cottages and farmhouses around Woodside can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
