Mastic sealing for commercial buildings in Selsey
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on shopfronts below residential blocks, communal kitchens and washrooms and external wall and movement joints, and the failures we are asked to look at most are occupiers reporting cold air round windows and damp patches beside frames. A specialist sealant contractor works differently from a general builder: on jobs in Selsey, preparation and product choice get the time they need.
Housing associations in towns like Selsey often run planned maintenance by estate or by block. Residents are notified through the association, and work moves building to building.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Substrate edges that need repairing first
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.
Joints and surfaces we work on
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Balcony and threshold joints
- External wall and movement joints
- Communal entrances and stairwells
Why it’s worth doing now in Selsey
Draughts round window perimeters cost occupiers comfort and the windows typically get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. In Selsey, as anywhere, the simplest time to fix a failed joint is before it leaks. Once water gets in, there’s drying out and making good as well.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

How the job changes by surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.

What we are called out for in Selsey
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Any of the following is a good reason to get the joints checked over:
- Complaints coming in block by block
- Worn sealant at communal door frames
- The same joint failures repeated across a portfolio
- Draughts at frames across a block
Property owners at sites such as Selsey Business Centre, less than half a mile south-west of Selsey, can have mastic renewed between lettings.
What your quote should include
- Is the sealant right for the movement and the substrate?
- What level of public liability insurance do they hold?
- Will failed sealant be removed rather than covered?
- Will CSCS-carded applicators be on site?
Questions about Selsey
Does your area include sites such as Selsey Business Centre, near Selsey?
Yes, sites like Selsey Business Centre are within our area, along with the rest of Selsey. Send details of the unit and the work through our quote form for a quick quote.
Does the sea air around Selsey change the choice of sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Who decides which product is used?
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.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Mastic sealing around Selsey: points for this area
Selsey sits close to the coast, within about 1 mile. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, so it’s worth inspecting those sides more often. Central London is about 61 miles from Selsey. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.
If you are responsible for a building such as St Peter's Church, frame and door mastic needs the same attention as any other property. Schools and community buildings such as Seal Primary Academy need frame and external mastic kept sound like any building.
