How we handle window mastic in Wimbledon Park
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for gaps where the sill meets the wall and black, perished sealant on frames, on patio & French doors, timber windows & doors and aluminium frames.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, letting in draughts and water.
All our work is covered by a one-year guarantee.

Frames and glazing around Wimbledon Park
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. Historic houses like Southside House (about 1.8 miles south-west) are a reminder that the area around Wimbledon Park 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.
For an older house near a landmark such as Church of St Luke, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. As a London address, Wimbledon Park can be tricky for parking: let us know about parking bays, permits or a driveway.

What else we do in Wimbledon Park
How we quote for window mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- How many areas need sealing
- When we can work, for business premises
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- How we’d reach the joints
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- Where the job is, and your postcode
Asking for a quote is easy: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Condensation trapped between the panes
- A sash or casement that will not close properly
- Damp problems in the wall away from the window
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

When to call us in Wimbledon Park
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
The most common problems we see are:
- Untidy mastic left by window fitters
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
- White mastic on grey or black frames
If you let a flat or house near Earlsfield station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

- What the quote includes, VAT included or not
- What insurance they hold
- Whether all the old sealant comes out first
Surface by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
What happens on the day
The work is kept neat 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. In Wimbledon Park, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- 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.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

Advice
Aftercare tips
To keep the joints looking good and working properly:
- Walk round the house once a year and look at the joints
- Do not paint over the silicone
- Avoid harsh chemicals near the mastic
- Air rooms to keep condensation down around windows
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Why deal with it now?
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear price before we start.
What you get with us
- Neat joints and a tidy finish
- A choice of colours where the product allows
- Domestic, commercial and hotel work
- 12-month guarantee on every job

FAQs for Wimbledon Park
Is parking an issue for window mastic in Wimbledon Park?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Is Wimbledon Park in your area for window mastic?
Yes. We work across London and the South East, and Wimbledon Park is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Can you seal the gap between the frame and the plaster indoors?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Is the work guaranteed?
Yes, with our 12-month guarantee. A yearly look at the joints helps them last.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
How long will my window job take?
A handful of frames is a short visit. You’ll get a timescale with the quote.
