Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Maintenance after handover
After handover, a little attention goes a long way:
- Share your contractor requirements early
- Reduce knocks to communal area joints
- Keep a record of when each building was resealed
- Make it easy for occupiers to report draughts
Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
Mastic sealing for commercial buildings in Fontwell
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. Site teams most often ask us about patchy repairs in mismatched sealant and occupiers reporting cold air round windows, across communal entrances and stairwells, balcony and threshold joints and communal kitchens and washrooms. A single leaking joint is often how a building in Fontwell first comes to us: we look at the rest while we’re there and tell you what we find.
Around smaller places like Fontwell, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Looking after buildings in and around Fontwell
At about 51 miles from central London, Fontwell is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. Six care or nursing homes sit less than 2 miles from Fontwell. Care home owners need frame and external mastic kept sound without unsettling residents.
Buildings close to stations like Barnham station, 1.6 miles south of Fontwell, are often flats over shops, with frame mastic to keep sound.

Advice
When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

- Broken glass or failed sealed units
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.
