Two Mile Ash Window Mastic
Window mastic in Two Mile Ash from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Cold air getting in at the frame edge
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a smaller place like Two Mile Ash, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Window mastic for homes and businesses in Two Mile Ash
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. Typical jobs include damp patches on the reveal after heavy rain and black, perished sealant on frames, across composite doors, window sills and timber windows & doors.
In smaller places like Two Mile Ash, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
Each job carries a 12-month guarantee, large or small.

How it works
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. Parking around Two Mile Ash is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- 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 earlier repairs to the joints
- Let us know about stairs, lifts or work at height

Signs you need window mastic in Two Mile Ash
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
These are the problems we are asked about most:
- Old mastic that has gone black or come away
- Draughty joints inside around the window
- Cracked sealant at the sill ends
- Hard, cracked sealant around windows
If you live in an older home near Church of the Holy Cross, the joint between an old wall and a newer frame is generally the first place rain gets in.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Make sure the drainage slots are not blocked
- Avoid blasting the frames with a pressure washer
- Paint up to the joint, not over it
- Avoid harsh chemicals near the mastic
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
What window mastic looks like in Two Mile Ash
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Linford Manor (about 2.8 miles north-east) are a reminder that the area around Two Mile Ash has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

When something else is needed

- A sash or casement that won’t close properly

- Draughts through the window seals rather than the frame
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Window sills
- Timber windows & doors
- Aluminium frames
- uPVC windows
- Composite doors
- Patio & French doors
What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
