Window & door mastic in Eddington, West Berkshire
Window mastic in Eddington from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Draughty joints inside around the window
- Mastic that’s falling out in pieces
- Cold air getting in at the frame edge
When to call us in Eddington
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
If you can see any of these, it’s time to have the joints looked at:
- Damp patches on the reveal after heavy rain
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
- Black, perished sealant on frames
For site and facilities teams at buildings such as Hungerford Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. In a small place like Eddington, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

How long does it take to reseal the windows on a house?

Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Damp coming through the wall itself rather than the frame joint
- A failed sealed unit that has misted up
- Soft or decayed wood in the frame
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

Leave it or put it right?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Where a wall is exposed, as many are in small places like Eddington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Window mastic in Eddington: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Hungerford Methodist Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Hungerford station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the job changes by surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as that is a job for a joiner.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
