Professional window mastic in and around Hazelwood, with old sealant always removed completely.
- Gaps between the frame and the inside reveal

What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a morning for a couple of windows and a door. In a small place like Hazelwood, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

About our window mastic in Hazelwood
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, call 0345 464 0079 or email us with the number of frames and any access details. We work on uPVC windows, window sills and composite doors, and common reasons people get in touch are gaps where the sill meets the wall and white mastic on grey or black frames.
Homes in small places like Hazelwood often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Window mastic in Hazelwood: local notes
Historic houses like Down House (about 1 mile west) are a reminder that the area around Hazelwood has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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 Chelsfield station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Homes close to St Mary's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Quotes for window mastic in Hazelwood
You’ll get a clear quote before work begins. It takes into account:

What to tell us for a quote

- Whether it has been sealed before
Every job is quoted individually. Just phone 0345 464 0079 or email us with the details, and photos are welcome.
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
- Paint up to the joint, not over it
- Keep solvents and bleach off the sealant
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Hazelwood, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

Signs you need window mastic in Hazelwood
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Most people get in touch after spotting something like this:
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
- Whistling draughts around closed windows
- Black, perished sealant on frames
For site and facilities teams at buildings such as Downe Primary School, its window and door frames need their mastic kept sound, just like a home’s.
