About our window mastic in Acol
Frames and walls do not move together. 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 work on timber windows & doors, composite doors and patio & French doors, and the jobs we see most are untidy mastic left by window fitters and old mastic that has gone black or come away.
Outdoor sealant needs dry, clean surfaces, so work on frames around Acol is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Surface by surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Ventilate rooms so frames don’t stay wet inside
- Do not use solvent cleaners on the joint
- Clean frames with a soft cloth and soapy water
- Check the mastic once a year
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
FAQs for Acol
Is Acol within the area you cover?
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.
Does living near the coast affect window mastic in Acol?
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.
Do you have insurance?
Yes. We are fully insured.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Can new window sealant be painted?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we’ll choose accordingly.
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a small place like Acol, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or email us and we will talk you through it.

Window mastic in Acol: local notes
Acol is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Birchington-On-Sea station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around St Mildreds Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Acol is about 4 miles south-west of Margate, in Kent. From the centre of Acol to the outskirts, window mastic is available for homes and businesses alike, from flats and houses to offices and hotels.

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’re 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.

When to call us in Acol
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That is what backing rod is for.
Most people get in touch when they notice one of these:
- Rain getting in at the frame or under the sill
- Gaps where the sill meets the wall
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
Managing a site like Birchington Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
