What the job involves on each surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
Window mastic in Hollow Street
From a single sill to a whole house of windows, you’ll get a clear quote before any work starts. To get one, ring 0345 464 0079 or drop us an email with the number of frames and any access details. Typical jobs include damp patches on the reveal after heavy rain and sealant in the wrong colour for the frame, across patio & French doors, timber windows & doors and composite doors.
Homes in small places like Hollow Street 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Frames and glazing around Hollow Street
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Sturry station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Chislet Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Signs you need window mastic in Hollow Street
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Keep an eye out for these signs:
- Hard, cracked sealant around windows
- White mastic on grey or black frames
- Draughts coming in around windows and doors
- Draughty joints inside around the window
Homes close to Church of St Mary the Virgin include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Clear any debris from frame drain holes
- Don’t paint over the silicone
- Wipe condensation off the frames
- Repaint timber before it’s bare
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

What we can’t put right

What we do, step by step

- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
