Window mastic for homes and businesses in Havering-atte-Bower
Around Havering-atte-Bower we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include cold air getting in at the frame edge and draughty joints inside around the window, on window sills, timber windows & doors and uPVC windows.
Homes in small places like Havering-atte-Bower 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 stand behind the work with a one-year guarantee.

Common problems we fix in Havering-atte-Bower
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Rushed sealant from a window installation
- Water coming in at the bottom corners of a door
- Black, perished sealant on frames
- Draughty joints inside around the window
For landlords with property near Harold Wood station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before you book

What window mastic looks like in Havering-atte-Bower
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. Historic houses like Hare Hall (about 2.6 miles south) are a reminder that the area around Havering-atte-Bower has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St John the Evangelist include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Dame Tipping Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Can you help a landlord with a rental near Harold Wood station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Havering-atte-Bower?

What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
Can you reach windows above the ground floor?
Yes, in most cases. We plan safe access before the job.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Havering-atte-Bower.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In a small place like Havering-atte-Bower, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before work begins.

What the job involves on each surface
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, 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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
