- Whistling draughts around closed windows
- Leaking joints at the ends of sills
- Sealant in the wrong colour for the frame
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Window mastic in Binfield Heath, done properly
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. Typical jobs include hard, cracked sealant around windows and leaking joints at the ends of sills, across timber windows & doors, window sills and composite doors.
Homes in small places like Binfield Heath 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Binfield Heath 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 Greys Court (about 3.3 miles north) are a reminder that the area around Binfield Heath 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.
Letting a property close to Shiplake station? Then renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Shiplake Church of England School, the mastic around its windows and doors needs looking after like any other building’s.

Work for landlords, hotels and businesses
We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Different surfaces, different methods
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.
What we do, step by step
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a morning for a couple of windows and a door in most cases. In a small place like Binfield Heath, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- 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.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Mention if the joints have been sealed before

Advice
Common problems we fix in Binfield Heath
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Most people get in touch after spotting something like this:
- Mastic that has split away from the wall
- Sealant in the wrong colour for the frame
- Leaking joints at the ends of sills
- Water coming in at the bottom corners of a door
For an older house near a landmark such as All Saints Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Which colour the sealant will be
- How the surfaces are prepared before sealing
- How much experience the applicator has

Binfield Heath questions
Can you help a landlord with a rental near Shiplake station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Will you come out to Binfield Heath?
Yes, Binfield Heath is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you match the sealant to my frames?
Generally, yes. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
Do you work on first-floor windows?
Yes, in most cases. We plan safe access before the job.
