Window Mastic in Wonersh
Window and door frames in Wonersh need attention? We cut out the old, prepare the joints and apply the right sealant.
- Water coming in at the bottom corners of a door
- Mastic that has split away from the wall
- Gaps where the sill meets the wall
Window mastic in Wonersh
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on aluminium frames, timber windows & doors and uPVC windows, and the jobs we see most are rushed sealant from a window installation and old mastic that has gone black or come away.
Around Wonersh, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Your questions about window mastic in Wonersh
Do you cover Wonersh for window mastic?
Yes. Our work covers London and the South East, and Wonersh is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Will you come out to Wonersh?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Can you get sealant to suit coloured frames?

Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Do you seal inside as well as outside?

Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
Surface by surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
The process
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Wonersh, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit

Advice
What we’re called out for in Wonersh
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
People usually contact us after spotting one of these:
- Gaps left after new windows were fitted
- Rain getting in at the frame or under the sill
- Mastic that has split away from the wall
- Draughty joints inside around the window
For site and facilities teams at buildings such as Bramley CofE Aided Infant School and Nursery, the mastic around its windows and doors needs looking after like any other building’s.
Before booking anyone
- Is the old sealant removed completely?
- How much experience the applicator has
- What preparation is included
- Which colour the sealant will be
Honest limits
To be straight with you, some problems need a different trade:
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
- Broken hinges, locks or handles
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.

What window mastic looks like in Wonersh
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Chilworth Manor (about 1.7 miles north) nearby, there’s older building stock in the area around Wonersh as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Wonersh United Reformed Church, the joint between an old wall and a newer frame is normally the first place rain gets in. If you let a flat or house near Chilworth station, renewing tired window mastic between tenants heads off draught and damp complaints.

What else we do in Wonersh
Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
