About our window mastic in Gomshall
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on composite doors, aluminium frames and patio & French doors, and common reasons people get in touch are draughts coming in around windows and doors and draughty joints inside around the window.
Homes in small places like Gomshall 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.
Every job is covered by our one-year guarantee, wherever you are in Surrey.

Windows and doors in Gomshall
With historic houses such as Hatchlands Park (about 2.9 miles north) nearby, there’s older building stock in the area around Gomshall as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Shere CofE Aided Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Gomshall station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Why act early in Gomshall
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like Gomshall, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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. Everything old must be removed first.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A door that needs adjusting, rehanging or new seals
- A frame that has rotted at the joint
- Penetrating damp from a failed cavity tray or render

What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. Somewhere as small as Gomshall, 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.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions

Signs you need window mastic in Gomshall
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
The problems people normally mention when they call are:
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
For an older house near a landmark such as The Church of St James, the joint between an old wall and a newer frame is normally the first place rain gets in.
What your quote should include
- What insurance they hold
- Is VAT in the price?
- Which colour the sealant will be
- What happens if they find a problem under the old sealant
Surface by surface
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we’ll tell you before going ahead, as a joiner will need to deal with it.
