Window mastic for homes and businesses in Wallend
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we will tell you. We work on composite doors, patio & French doors and timber windows & doors, and people most often call us about mastic that has split away from the wall and gaps left after new windows were fitted.
Somewhere as small as Wallend, 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.
There’s a 12-month guarantee on every job, large or small.

The process
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of frames, longer for a whole house. In a small place like Wallend, access is usually 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.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- 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.

Frames and glazing around Wallend
Wallend is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as St James Church of England Primary Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St James, the joint between an old wall and a newer frame is normally the first place rain gets in.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Surface by surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that without cracking.
Common questions in Wallend
Is Wallend within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Sheerness-On-Sea station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Signs you need window mastic in Wallend
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. That is what backing rod is for.
Common reasons people contact us include:
- Rushed sealant from a window installation
- Draughty joints inside around the window
- Draughts coming in around windows and doors
- Black, perished sealant on frames
If you let a flat or house near Sheerness-On-Sea station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
