About our window mastic in Woolton Hill
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you’re dealing with white mastic on grey or black frames and gaps left after new windows were fitted, we can help.
In a village or hamlet like Woolton Hill, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All our work comes with a one-year guarantee, wherever you are in West Berkshire.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What the job involves on each surface
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall.
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Draughts through the window seals rather than the frame
- Faulty window hardware
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
What we seal
- Window sills
- Aluminium frames
- Patio & French doors
- Composite doors
- Timber windows & doors
- uPVC windows
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
- Make sure the drainage slots aren’t blocked
- Clean frames with a soft cloth and soapy water
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

Why it’s worth doing now in Woolton Hill
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Where a wall is exposed, as many are in small places like Woolton Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Woolton Hill homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Stargroves (about 1.6 miles west) are a reminder that the area around Woolton Hill has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Newbury station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Woolton Hill Junior School, 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 Thomas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Woolton Hill, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Let us know about parking restrictions
