Window mastic for homes and businesses in Sulhamstead
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. Typical jobs include damp patches on the reveal after heavy rain and gaps where the sill meets the wall, across composite doors, uPVC windows and window sills.
Around Sulhamstead, 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 there’s a problem with it, please ring 0345 464 0079 or send us an email.

Sulhamstead homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Theale station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Church of St Peter, the joint between an old wall and a newer frame is normally the first place rain gets in.

Your questions about window mastic in Sulhamstead
Can you do window mastic in Sulhamstead?
Yes. We work across London and the South East, and Sulhamstead is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Do you work for landlords with property near Theale station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
How many windows can you do in a day?
Allow a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
For anyone letting property in or around Sulhamstead, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
What we are called out for in Sulhamstead
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. That’s what backing rod is for.
Any of these means the joints need attention:
- Draughty joints inside around the window
- Black, perished sealant on frames
- White mastic on grey or black frames
- Gaps left after new windows were fitted
Managing a site like Sulhamstead and Ufton Nervet School? Then its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Whether the sealant suits the joint
- What insurance they hold
- What the cure time is
- Whether they seal over old material or remove it

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What happens if it’s left?
The work is quick compared with the damage it prevents: it takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. Around Sulhamstead, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours for a handful of frames, longer for a whole house. Somewhere like Sulhamstead needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
