Quotes for window mastic in Brabourne Lees
The quote reflects the job in front of us. We take into account:
- Whether old sealant or filler has to be cut out

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. Your quote takes all of that into account.

Surface by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Aftercare tips
To keep the joints looking good and working properly:
- Repaint timber before it’s bare
- Wash the frames with mild soapy water
- Keep paint off silicone joints
- Avoid harsh chemicals near the mastic
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
How it works
Before we leave, we go over the finished joints with you. The work normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the amount of work. For a village or hamlet like Brabourne Lees, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Common problems we fix in Brabourne Lees
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Keep an eye out for these signs:
- Whistling draughts around closed windows
- Black, perished sealant on frames
- Rushed sealant from a window installation
- Gaps between the frame and the inside reveal
Letting a property close to Westenhanger station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before you book

- Are they insured?

Windows and doors in Brabourne Lees
With historic houses such as Westenhanger Castle (about 3.2 miles south-east) nearby, there’s older building stock in the area around Brabourne Lees as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among 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 Mary include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Smeeth Community Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
