Our commercial sealant contractors service in BN42
A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. Most enquiries involve untidy joints in a reception, shop floor or lobby and damp patches where an external joint has failed, across kitchen worktops and splashbacks, floor and threshold joints and washrooms and tea points.
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish.
- First, details come to us: photos, drawings or a schedule of the areas.
- Next comes a diagnosis and a fixed quote.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- We strip the failed bead and prepare both faces of the joint.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.

Local landmarks in Southwick

Green spaces nearby include Shoreham Beach and Thundersbarrow Hill.
Shops, offices and hotels in BN42
Commercial buildings across BN42 range from older premises altered many times to recent units on business parks. Each building needs the right product for its surfaces, from stone and brick to coated aluminium and laminate.
Around the motorway corridors of the South East, business parks and industrial estates are common, and BN42 is part of the area we cover. BN42 includes coastal places, where facades, frames and external slabs take more weather than inland. Product choice and joint preparation matter more there.
Southwick: Shops and cafés around stations like Southwick station (to the south of Southwick) trade from early, so work is timed around them. A business with units at Grange Industrial Estate and Dolphin Industrial Estate needn’t use two contractors for its sealant.
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:
- Leaks from pipework, wastes or valves (that’s plumbing)
- A failed roof covering or waterproofing membrane
- Walls or slabs moving more than any sealant can take
Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around BN42. One quote can cover more than one site, which keeps the paperwork simple.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Any access equipment needed
- How much there is to seal
- How much existing material needs removing
- Backing rod, priming and other preparation
A quote for sealant joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Whether an asbestos survey exists
- Access details, including height
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or send details through our quote form to discuss it first.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Respect the cure time before reopening an area
- Make sure ventilation in wet areas is switched on and working
- Keep abrasive pads and scrapers off resealed joints
Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.
Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.
Common problems we fix in BN42
When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. It’s one of the commonest faults we find on earlier work.
It’s worth sending us details if you spot any of the following:
- Sanitary sealant that has gone black and patchy
- Expansion joints with the sealant torn out
- Smeared sealant across finishes from a rushed job
- A top-up bead over failed sealant, now lifting
Common questions from BN42 clients
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Is your work guaranteed?
Each job sits under our 12-month guarantee. Keeping joints clean and inspected helps them last well beyond that.
Can you handle sealant work across several sites?
Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you check for asbestos before removing sealant?
It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.
How do we get a quote?
Photos, drawings or a schedule of the joints are normally enough to start through our quote form. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.
