About our window mastic in Chobham
Homes in Chobham have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you’re dealing with black, perished sealant on frames and cracked or shrunken mastic around the frame, we can put it right, on patio & French doors, composite doors and timber windows & doors alike.
Many houses in smaller places like Chobham have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
You get a 12-month guarantee, the same in Chobham as everywhere else we work.

The process
All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. Parking around Chobham is usually 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.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
- Tell us about any water getting in

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Wipe condensation off the frames
- Check the mastic once a year
- Do not aim a pressure washer at the joints
- Don’t use solvent cleaners on the joint
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

Window mastic in Chobham: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Botleys Mansion (about 3.2 miles north-east) are a reminder that the area around Chobham 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.
If you live in an older home near Church of St Lawrence, the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Longcross station, renewing tired window mastic between tenants heads off draught and damp complaints.

How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Composite doors
Front doors take the weather head on. Those corners get the most care.
FAQs for Chobham
Can you do window mastic in Chobham?
Yes. Our work covers London and the South East, and Chobham is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
I let a flat near Longcross station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Does the work come with a guarantee?
Yes. Every job comes with our 12-month guarantee, and we are fully insured.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Which products 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.
Can resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Leave it or put it right?
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. Around Chobham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Do you need window mastic in Chobham?
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
Most people get in touch after spotting one of these:
- Draughts coming in around windows and doors
- Draughty joints inside around the window
- Rushed sealant from a window installation
- Sealant in the wrong colour for the frame
Managing a site like St Lawrence CofE (Aided) Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
