Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Older cottages and farmhouses around Redbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.

About our window mastic in Redbridge
Around Redbridge we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Common call-outs are for damp patches on the reveal after heavy rain and cracked internal joints between frame and plaster, on patio & French doors, aluminium frames and window sills.
Homes in small places like Redbridge 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.
Big or small, you get the same one-year guarantee in Redbridge and across Oxfordshire.

Do you need window mastic in Redbridge?
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
People generally contact us when they notice one of these:
- Untidy mastic left by window fitters
- Cracked sealant at the sill ends
- Black, perished sealant on frames
- Cracked internal joints between frame and plaster
Schools such as New Hinksey Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What the job involves on each surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Looking after it afterwards
So the new joints stay in good condition:
- Look round the frames every year or so
- Air rooms to keep condensation down around windows
- Keep paint off silicone joints
- Keep solvents and bleach off the sealant
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
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.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.
What we seal

Windows and doors in Redbridge
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Holywell Manor (about 1.9 miles north) are a reminder that the area around Redbridge 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.
Rented homes near Oxford station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as St Luke's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. For a village or hamlet like Redbridge, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints

Your questions about window mastic in Redbridge
Do you work for landlords with property near Oxford station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Redbridge?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. We will tell you how long your job needs when we quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Redbridge.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
