Effingham Window Mastic
Problem with your window and door frames in Effingham? We cut out the old, prepare the joints and apply the right sealant.
- White mastic on grey or black frames
- Cracked sealant at the sill ends
- Gaps between the frame and the inside reveal
Leave it or put it right?
The work is quick compared with the damage it prevents: the visit takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Effingham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits. We’ll send you a clear quote for the lot.
Why book with us
- Anti-fungal sanitary silicone in wet areas
- Domestic, commercial and hotel work
- We never seal over old sealant
- An ARBOMaster approved applicator

Window mastic in Effingham, done properly
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. We’re often asked to deal with sealant in the wrong colour for the frame and draughty joints inside around the window, on composite doors, patio & French doors and window sills.
Somewhere as small as Effingham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Big or small, you get the same one-year guarantee in Effingham and across Surrey.

Do you need window mastic in Effingham?
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
People normally contact us when they notice one of these:
- Gaps between the frame and the inside reveal
- Damp patches on the reveal after heavy rain
- Draughts coming in around windows and doors
- White mastic on grey or black frames
For site and facilities teams at buildings such as St Lawrence Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not aim a pressure washer at the joints
- Clean frames with a soft cloth and soapy water
- Do not paint over the silicone
- Clear any debris from frame drain holes
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Effingham, 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.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- 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
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in

How we quote for window mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- Mould in or behind the old joints
- The product the joint needs
- How many rooms, windows or areas are involved
- Access and height
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.
Asking for a quote
To make quoting easier, please include:

How the job changes by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
Effingham homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Polesden Lacey (about 1.4 miles south-east) are a reminder that the area around Effingham has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near Bookham station, renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as Church of St Lawrence, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
