Frimley Green Window Mastic
We cover Frimley Green for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Cracked or shrunken mastic around the frame
- Black, perished sealant on frames
- Damp patches on the reveal after heavy rain
Window mastic for homes and businesses in Frimley Green
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you have draughty joints inside around the window and cracked sealant at the sill ends, we can help, on timber windows & doors, patio & French doors and window sills alike.
In smaller places like Frimley Green, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
Whatever the size of the job, you get the same 12-month guarantee.

Landlords, agents and businesses in Frimley Green
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
When to call us in Frimley Green
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
People normally contact us after spotting one of these:
- Sealant in the wrong colour for the frame
- Cracked or shrunken mastic around the frame
- Cold air getting in at the frame edge
- Cracked internal joints between frame and plaster
Schools such as Cross Farm Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What window mastic looks like in Frimley Green
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 live in an older home near Church of St Andrew, the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Farnborough North station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Quotes for window mastic in Frimley Green
For a quick quote, just ask. The main things that affect it are:
- Any mould that needs treating
- Working hours on commercial sites
- The size of the job
- How easy the joints are to reach
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
To make quoting easier, let us know:
- Photos by email, if that is easy
- Roughly how big the job is
- If someone has resealed it before
- What’s wrong with the joints now
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or drop us an email.
How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. In a smaller place like Frimley Green, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks

Advice
Surface by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we will tell you before going ahead, as that’s a job for a joiner.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep paint off silicone joints
- Keep jet washers away from the mastic
- Air rooms to keep condensation down around windows
- Look round the frames every year or so
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or email us.
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.
