Commercial sealant contractors in BN17: how it works
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on movement joints in walls and floors, window and door perimeters and washrooms and tea points, and the failures we’re asked to look at most are mouldy silicone around WCs, urinals and vanity tops and hardened, chalky sealant on south-facing or exposed elevations.
Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
What you will pay
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Why appoint us
- Fixed quotes based on photos, drawings or a visit
- One contact handling all your sites
- CHAS accredited contractor
- Fully insured, including public liability cover
Quotes
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Local landmarks in Littlehampton
We work on buildings around River Beach Primary School, New Inn Hotel and Littlehampton College and the streets around them. Other local landmarks include The Parish Church of St Mary the Virgin (under half a mile south-west), The Littlehampton Academy (under half a mile north) and Mewsbrook Park (0.6 miles south-east). The nearest railway station is Littlehampton station, about 0.7 miles west. A little further out are Zachary Merton Hospital (1.4 miles east) and Lyminster Siege Castle (2.8 miles north). Open spaces near Littlehampton include Highdown Hill and WWT Arundel.
Shops, offices and hotels in BN17
Across BN17, from Littlehampton, Rustington and Wick to the smaller places between, commercial buildings run from high-street shops and offices to hotels, schools and business parks. Because we cover all of it, multi-site occupiers can bring every building under one quote.
The South East has large numbers of business parks and industrial estates, especially around the motorway corridors, and we cover BN17 along with the rest of the region. In the parts of BN17 near the sea, the elevations facing the weather are where sealant gives up first.
Littlehampton: Industrial estates such as Lineside Road Industrial Estate (to the west of Littlehampton) have offices, trade counters and welfare areas whose sealant ages like any other building’s. Refits at hotels like Victoria Hotel, less than half a mile to the south-west of Littlehampton, bring joints at vanity tops, bars and reception desks that guests see every day.
How the job changes by surface
Movement joints in walls and floors
A trafficked floor joint needs a different product from a wall joint. We will recommend the right filler or sealant for the traffic and movement.
Fire-rated seals where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps.
What we’re called out for in BN17
If sealant tears through its centre, it has failed cohesively. Usually the movement was too much for the sealant chosen because the bead was too thin, the joint over-stretched or the movement class wrong. Replacing it like for like rarely holds, which is why we look at the joint design as well.
Site and facilities staff are often the first to spot these:
- Gaps behind commercial kitchen worktops and sinks
- Weathered facade sealant that no longer flexes
- Expansion joints with the sealant torn out
- Mouldy silicone around WCs, urinals and vanity tops
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Faulty windows rather than failed perimeter sealant
- Old mastic that tests positive for asbestos
General trades versus a specialist
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Work for main contractors and building owners
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
Questions about BN17
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Is the old sealant taken out first?
Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.
Do you work in BN17?
Yes. Sites across BN17 are covered.
Can areas stay open during the work?
Most of the buildings we work in stay occupied. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing for as long as the cure needs.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you check for asbestos before removing sealant?
It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
