Your questions about window mastic in Compton
Is Compton in your area for window mastic?
Yes, Compton is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Compton?
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.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Window mastic in Compton, done properly
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. We work on patio & French doors, timber windows & doors and uPVC windows, and the jobs we see most are sealant in the wrong colour for the frame and mastic that has split away from the wall.
Around Compton, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months.

Windows and doors in Compton
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Mary and St Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Leave it or put it right?
Choosing the product is half the job. 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. Older cottages and farmhouses around Compton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why Compton clients choose us
- An ARBOMaster approved applicator
- Trusted Arbo and Everbuild sealants
- Sanitary silicone with an anti-fungal additive in wet areas
- A choice of colours where the product allows

What affects the cost of window mastic
Call for a quick quote. What matters most is:
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- Any mould that needs treating
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- If someone has resealed it before
- Whether it’s a home or a business
If you’re in Compton and need window mastic, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before we start.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a morning for a couple of windows and a door, including the tidy-up. Somewhere as small as Compton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Mention any tricky access
Ask for a quote
Getting a quote is simple: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll take it from there.

Signs you need window mastic in Compton
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
Keep an eye out for any of the following:
- White mastic on grey or black frames
- Cracked or shrunken mastic around the frame
- Black, perished sealant on frames
- Gaps where the sill meets the wall
Schools such as Compton C.E. Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- Who turns up on the day
- How the surfaces are prepared before sealing
- Whether VAT is included
- How long to leave it before use
How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Composite doors
Front doors take the weather head on. We pay most attention there.
