How we handle mastic sealing in Brighton and Hove
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. We work on window and door perimeters on blocks, communal kitchens and washrooms and balcony and threshold joints, and the failures we are asked to look at most are movement joints with sealant missing and occupiers reporting cold air round windows. For commercial sealant work in Brighton and Hove, you deal with one contact from quote to sign-off, whether it’s one building or several.
In Brighton and Hove, as in most towns, a block may have frames from several eras, so mastic around them can be of mixed age and quality. A look at the whole building shows which joints need doing now.
A 12-month guarantee applies to all our work in Brighton and Hove. If an installation problem shows up, speak to us on 01277 525 020 or send details through our quote form and we will arrange a return visit.

Planned mastic for Brighton and Hove portfolios
Brighton and Hove sits close to the coast, within about 1 mile. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, so it’s worth inspecting those sides more often. The 2 miles around Brighton and Hove include two care or nursing homes. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
Older community buildings, Holy Cross Church among them, often have frames of mixed ages whose mastic varies. Owners of student blocks near University of Brighton Moulesecoomb Campus (to the east of Brighton and Hove) can schedule frame and external mastic for the summer vacation. If you own or manage units on a site such as Portland Road Trading Estate, which lies west of Brighton and Hove, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

How the job changes by surface
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.
Commercial and mixed-use buildings
Commercial occupiers typically stay open during the work so the work is phased.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Leaks through the frame itself rather than the perimeter
- Glazing that needs replacing
If you’re not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
Where we work in Brighton and Hove
- External wall and movement joints
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Balcony and threshold joints
- Window and door perimeters on blocks
What happens if it’s left?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows and occupiers notice. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.
Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Aftercare for building managers
For the best life from the joints:
- Start inspections with the most exposed faces
- Keep bins and bikes away from communal door frames
- Make it easy for occupiers to report draughts
- Check sealant joints during planned building inspections
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.
Common questions from Brighton and Hove clients
Can you quote for a block close to Aldrington station?
Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Will you take on work at estates like Portland Road Trading Estate, close to Brighton and Hove?
Yes. We cover Brighton and Hove and the area around it, including industrial estates, business parks and retail parks such as Portland Road Trading Estate. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Can people stay in the building while you reseal?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.
Is Brighton and Hove in your area?
Yes. We cover Brighton and Hove, and you can give us a call on 01277 525 020 or email a schedule or drawings to get started.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
