About our window mastic in Warmlake
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include draughts coming in around windows and doors and black, perished sealant on frames, on patio & French doors, timber windows & doors and uPVC windows.
Homes in small places like Warmlake often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months.

Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.

Why it’s worth doing now in Warmlake
The work is quick compared with the damage it prevents: the visit takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Warmlake, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

What happens on the day
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes most of a day for a typical house, less for a few frames for a typical job. Somewhere like Warmlake needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.

How we quote for window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- Any working-time requirements on site
- How easy the joints are to reach
- How many rooms, windows or areas are involved
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.
Asking for a quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- What’s wrong with the joints now
For window mastic in Warmlake, call 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and you’ll get a clear quote before we start.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Warmlake 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. Historic houses like Stoneacre (about 2.1 miles north) are a reminder that the area around Warmlake has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Hollingbourne station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Sutton Valence Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Michael, the joint between an old wall and a newer frame is normally the first place rain gets in.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Clear any debris from frame drain holes
- Ventilate rooms so frames don’t stay wet inside
- Do not paint over the silicone
- Use gentle cleaners on frames and sealant
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
