Window mastic for homes and businesses in Cheriton
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on composite doors, uPVC windows and patio & French doors, and common reasons people get in touch are draughts coming in around windows and doors and sealant in the wrong colour for the frame.
Around Cheriton, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Common problems we fix in Cheriton
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
The problems people generally mention when they call include:
- Draughty joints inside around the window
- Hard, cracked sealant around windows
- Leaking joints at the ends of sills
- Mastic that’s falling out in pieces
For site and facilities teams at buildings such as All Soul's Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Questions from Cheriton
Does the coastal weather in Cheriton affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Cheriton?
Yes. Cheriton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can resealing stop a draught around my window?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
Different surfaces, different methods
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
What we do, step by step
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a few frames, or a day or more for a whole house from start to finish. For a job in Cheriton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Mention if the joints have been sealed before
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children

Advice
Window mastic in Cheriton: local notes
Cheriton is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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 Acrise Place (about 3.4 miles north) are a reminder that the area around Cheriton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of All Souls, the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Folkestone West station, renewing tired window mastic between tenants heads off draught and damp complaints.
Cheriton is about 1 mile west of Folkestone, in Kent.

Other landmarks nearby include Sandgate Castle (1 mile south) and Elham Valley Countryside Centre And Railway Museum (1.3 miles north-west). For a walk, there’s Sugar Loaf Hill.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Clear any debris from frame drain holes
- Do not use solvent cleaners on the joint
- Use gentle cleaners on frames and sealant
- Wipe condensation off the frames
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- A failed sealed unit that has misted up
- A frame that has rotted at the joint
- Worn gaskets, brush seals or a door that has dropped
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.
