Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What the job involves on each surface
Shop fronts and retail fit-outs
In retail, sealant is on show. Joints around counters, displays and shopfront frames have to look tidy as well as seal. Colour options are confirmed with the quote.
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean, which matters when environmental health officers look at a kitchen. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.
How we handle commercial sealant contractors in Tewin
Most of the buildings we seal stay open while we are there. Tell us your site hours and access windows and we will plan around them. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. Site teams most often ask us about frame mastic that has hardened and come away from the wall and black mould through washroom sealant that won’t clean off, across window and door perimeters, kitchen worktops and splashbacks and movement joints in walls and floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Tewin, preparation and product choice get the time they need.
If you look after more than one building near Tewin, the work can be planned as one programme, with one quote format and one point of contact.
Business units in the countryside around places like Tewin are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Advice
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Keep abrasive pads and scrapers off resealed joints
- Check sealant as part of routine building inspections
- Check the asbestos register before anyone disturbs old sealant in an older building
- Report cracked or peeling sealant early
Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just call 01277 525 020 or send details through our quote form for a quote.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to, which makes sound joints worth keeping on top of.

Your questions answered
Will our hotel in Tewin need to close for the work?
Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.
Is a smaller place like Tewin outside your area?
No. Places such as Tewin are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What site paperwork can you provide?
Send your site requirements with the enquiry, and the paperwork is confirmed with the quote. From you, we’ll need the asbestos information for older buildings and any site rules.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you take on work for an FM or managing agent?
Yes. Use our quote form to send the site details, or phone or email us, and we will confirm any paperwork you need with the quote.
Is your work guaranteed?
It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.
Why act early in Tewin
Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. Splitting the scope into now and later is often the sensible compromise. Converted and older buildings near places like Tewin tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, 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: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
