About our window mastic in Letcombe Bassett
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on aluminium frames, uPVC windows and patio & French doors, and common reasons people get in touch are white mastic on grey or black frames and water coming in at the bottom corners of a door.
Around Letcombe Bassett, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Your job is guaranteed for a year, as with all our work.

What affects the quote in Letcombe Bassett
We quote each job individually. This is what makes a difference:
- The old material and how stubborn it is
- Mould in or behind the old joints
- Whether the work is at height
- How many areas need sealing
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Any access issues, like height or stairs
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
We do not publish a price list, because every job is different. Instead, we give you a clear quote for your job. To arrange one, call 0345 464 0079 or email us.
How the job changes by surface
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall and tooled smooth.
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Leave it or put it right?
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Letcombe Bassett can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What you get with us
- White, clear, grey or coloured to suit, where the product allows

How it works

- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

Letcombe Bassett homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Michael include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Yes, Letcombe Bassett is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
How much does window mastic cost in Letcombe Bassett?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Will resealing my frames help with draughts?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Do you seal inside as well as outside?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Condensation trapped between the panes
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

Signs it’s time to call us include:
- Gaps left after new windows were fitted
- Leaking joints at the ends of sills
- Hard, cracked sealant around windows
- Cracked internal joints between frame and plaster
In and around Letcombe Bassett, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
