Mastic sealing in West Barnham, done properly
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you have repeated reactive repairs to the same buildings and failed external movement joints, we can help, whatever the surface. Facilities teams, main contractors and managing agents in West Barnham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Owners and agents with buildings around smaller places such as West Barnham tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

At about 52 miles from central London, West Barnham is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.

Why deal with it now?
Draughts round window perimeters cost occupiers comfort and the windows typically get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Converted and older buildings near places like West Barnham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

West Barnham: questions and answers
We manage a building near Barnham station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Can work in a care setting near West Barnham go ahead while residents are there?
Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.
Do you do block-wide mastic programmes?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Is West Barnham in your area?
Yes. Sites across West Barnham are covered, with one number for every area we cover.
Can you seal joints high up on a block?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
When something else is needed
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:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Misted or failed double-glazed units
- Failed window or door frames, which need a window contractor
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think before you book.
