Gatton Window Mastic
Problem with your window and door frames in Gatton? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Hard, cracked sealant around windows
- Gaps between the frame and the inside reveal
- Gaps left after new windows were fitted
How we handle window mastic in Gatton
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on window sills, aluminium frames and uPVC windows, and people most often call us about cold air getting in at the frame edge and water coming in at the bottom corners of a door.
Homes in small places like Gatton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Your questions about window mastic in Gatton
Is Gatton in your area for window mastic?
Yes. Our work covers London and the South East, and Gatton is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Gatton?
Yes, Gatton is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
What the job involves on each surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
When to call us in Gatton
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
Signs it’s time to call us include:
- Untidy mastic left by window fitters
- Draughts coming in around windows and doors
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
If you look after a building such as Lime Tree Primary School, its window and door frames need their mastic kept sound, just like a home’s.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Landlords, agents and businesses in Gatton
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- A door that needs adjusting, rehanging or new seals
- A sash or casement that will not close properly
- A frame that has rotted at the joint
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Windows and doors in Gatton
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.
If you live in an older home near St Andrew's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Merstham station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

- Any mould that needs treating
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out

How it works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work starts. The work usually takes most of a day for a typical house, less for a few frames. In a small place like Gatton, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
