Window mastic for homes and businesses in Aldermaston
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We are often asked to deal with white mastic on grey or black frames and mastic that’s falling out in pieces, across uPVC windows, patio & French doors and composite doors.
Around Aldermaston, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Your job is guaranteed for a year, as with all our work.

What window mastic looks like in Aldermaston
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Aldermaston C.E. Primary School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Aldermaston station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Church of St Mary the Virgin include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Letting agents and landlords in Aldermaston can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Leave it or put it right?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Older cottages and farmhouses around Aldermaston can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What else we do in Aldermaston
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The process
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take a morning for a couple of windows and a door, and we explain the cure time before we leave. In a small place like Aldermaston, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in

Surface by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
