Common problems we fix in Rye
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
Look out for these signs:
- Black, perished sealant on frames
- Mastic that has split away from the wall
- A bead that does not match the frame
- Cracked sealant at the sill ends
Managing a site like Rye Community Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Window mastic in Rye, done properly
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We are often asked to deal with whistling draughts around closed windows and gaps left after new windows were fitted, on composite doors, patio & French doors and timber windows & doors.
In a smaller place like Rye, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are, and we tell you how long to leave it before we go. For a job in Rye, 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.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Repaint timber before it’s bare
- Do not paint over the silicone
- Keep jet washers away from the mastic
- Check the mastic once a year
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
What happens if it’s left?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Homes in smaller places like Rye can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What you get with us

Rye: your questions answered
Does the coastal weather in Rye affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Can you help a landlord with a rental near Rye station?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
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 I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Rye.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before work begins.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Windows and doors in Rye
Rye is close to 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 Lamb House (about 0.1 miles south-east) are a reminder that the area around Rye has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Rye station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.
