How we handle window mastic in Three Chimneys
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, phone 0345 464 0079 or email us with the number of frames and any access details for window mastic in Three Chimneys. Common call-outs are for rushed sealant from a window installation and cracked internal joints between frame and plaster, across uPVC windows, window sills and composite doors.
Around Three Chimneys, 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.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How the visit works
We keep the work tidy and contained to the area we’re working on. The job generally takes a morning for a couple of windows and a door, and we explain the cure time before we leave. Somewhere as small as Three Chimneys, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Let us know about parking restrictions

Looking after it afterwards
After the cure time, these simple habits help:
- Ventilate rooms so frames don’t stay wet inside
- Make sure the drainage slots are not blocked
- Wash the frames with mild soapy water
- Keep jet washers away from the mastic
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 old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.

What the job involves on each surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as that is a job for a joiner.
What happens if it’s left?
Resealing frames is a short job: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. Around Three Chimneys, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Do you need window mastic in Three Chimneys?
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
If you can see any of these, it’s time to have the joints looked at:
- Draughty joints inside around the window
- Black, perished sealant on frames
- Rushed sealant from a window installation
- Mastic that has split away from the wall
Letting a property close to Headcorn station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Three Chimneys homes and the weather
