Window mastic for homes and businesses in St Margaret's at Cliffe
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have draughty joints inside around the window and damp patches on the reveal after heavy rain, we can put it right, whatever the surface.
In smaller places like St Margaret's at Cliffe, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Common questions in St Margaret's at Cliffe
Do you work for landlords with property near Martin Mill station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is window mastic in a coastal place like St Margaret's at Cliffe any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee, and we’re ARBOMaster approved applicators.
Are you fully insured?
Yes. We’re fully insured.
Will resealing my frames help with draughts?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Windows and doors in St Margaret's at Cliffe
St Margaret's at Cliffe is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Walmer Castle (about 3.5 miles north) are a reminder that the area around St Margaret's at Cliffe has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Margaret, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Martin Mill station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Do you need window mastic in St Margaret's at Cliffe?
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
The most common problems we see are:
- Draughts coming in around windows and doors
- Draughty joints inside around the window
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
Schools such as St Margaret's-at-Cliffe Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The process
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job usually takes anything from an hour or two to a full day, depending on how many frames there are. In a smaller place like St Margaret's at Cliffe, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, we go round the frames with you and agree the list.
- 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.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
- Let us know about earlier repairs to the joints

How the job changes by surface
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
