Leave it or put it right?
Draughts round window perimeters cost occupiers comfort and the windows usually get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

How we handle mastic sealing in Petts Wood
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. Site teams most often ask us about draught complaints from residents or tenants and a mix of products and colours from past repairs, across communal kitchens and washrooms, external wall and movement joints and communal entrances and stairwells. Most enquiries from Petts Wood start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. Work is planned with the agent so residents get notice and access is arranged in advance.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Share your contractor requirements early
- Encourage occupiers to report problems at frames
- Share the asbestos register when you send details
- Avoid piecemeal callouts where you can
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
One failed perimeter typically means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
