Window mastic in St Peter's
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. Typical jobs include rushed sealant from a window installation and mastic that’s falling out in pieces, on aluminium frames, timber windows & doors and patio & French doors.
Homes around St Peter's range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
Our work is backed for twelve months.

Do you need window mastic in St Peter's?
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
Most people get in touch after spotting something like this:
- Rushed sealant from a window installation
- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
- Mastic that’s falling out in pieces
Rented homes near Broadstairs station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- Who turns up on the day
- Whether VAT is included
- What product goes in the joint
- Are they insured?
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Aftercare tips
A little care helps the new joints last. We recommend:
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
- Keep solvents and bleach off the sealant
- Paint up to the joint, not over it
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Why act early in St Peter's
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Homes in smaller places like St Peter's can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Surface by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.
How it works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. Parking around St Peter's is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks

St Peter's: your questions answered
Can you help a landlord with a rental near Broadstairs station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Will you come out to St Peter's?
Yes, smaller places are covered as well as towns. We work across 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?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
Can I paint over the new sealant?
Not usually, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Window mastic in St Peter's: local notes
St Peter's 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. That is hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Quex Park (about 4.2 miles west) are a reminder that the area around St Peter's 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 is traditional sand mastic.
For site and facilities teams at buildings such as Dane Court Grammar School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Parish Church of St Peter the Apostle, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
