Window mastic in Winterbourne
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on aluminium frames, window sills and timber windows & doors, and people most often call us about water coming in at the bottom corners of a door and a bead that doesn’t match the frame.
In a village or hamlet like Winterbourne, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months.

Why act early in Winterbourne
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. Around Winterbourne, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Landlord and commercial work in Winterbourne
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What we are called out for in Winterbourne
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
The most common problems we see are:
- Gaps between the frame and the inside reveal
- Cracked sealant at the sill ends
- Cracked or shrunken mastic around the frame
- Old mastic that has gone black or come away
Letting a property close to Selling station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before you book
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
- Who turns up on the day
- The length of the guarantee
How the visit works
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take most of a day for a typical house, less for a few frames. In a small place like Winterbourne, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, 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.
Before we arrive
- Let us know about parking restrictions
- Clear the area around the work
- Keep pets and children clear of the area while we work

Advice
Different surfaces, different methods
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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.
Questions from Winterbourne
Do you work for landlords with property near Selling station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Is Winterbourne within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Do you have insurance?
Yes. We are fully insured for every job we do.
Do you guarantee window mastic?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Can I paint over the new sealant?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Winterbourne homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Christ Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Boughton-under-Blean and Dunkirk Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
