Surface by surface
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
How we handle mastic sealing in Burnham
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. We work on external wall and movement joints, balcony and threshold joints and window and door perimeters on blocks, and what we’re called in for most is window mastic that has split and shrunk and occupiers reporting cold air round windows.

Common questions from Burnham clients
Can you quote for a block close to Burnham station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Can work in a care setting near Burnham go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.
Can you plan resealing across several buildings?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you work in Burnham?
Yes. We cover Burnham, and you can call the office on 01277 525 020 or email drawings and photos to get started.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

After the work
Regular inspection catches problems early. Specifically:
- Track which buildings were done and when
- Make mastic part of routine maintenance checks
- Plan resealing building by building rather than complaint by complaint
- Reduce knocks to communal area joints
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Honest limits
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Masonry that has broken away beside the joint
- Materials that need asbestos testing before work
- Frames that are rotten, warped or broken
If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Site staff or a sealant specialist?
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a job in Burnham, the main thing is a clear picture of the work, so send photos of each area. You will then get a fixed price for the work.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
