Commercial sealant contractors in TN21: how it works
Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in TN21, call the office on 01277 525 020 or use the quote form with the site addresses. We work on kitchen worktops and splashbacks, washrooms and tea points and external facade joints, and the usual reasons a site gets in touch are gaps behind commercial kitchen worktops and sinks and damp patches where an external joint has failed.
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
What affects the price in TN21
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Commercial sealant contractors across TN21: the area picture
The commercial stock in TN21 mixes older town-centre buildings with newer offices and units, in places such as Heathfield, Sandy Cross and Horam and beyond. Each building needs the right product for its surfaces, from stone and brick to coated aluminium and laminate.
The South East has large numbers of business parks and industrial estates, especially around the motorway corridors, and we cover TN21 along with the rest of the region.
Heathfield: If you run a unit on an estate such as Station Road Industrial Estate, less than half a mile to the north-west of Heathfield, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. If you have premises on more than one site, say at Station Road Industrial Estate and Ghyll Road Industrial Estate, one contractor and one quote can cover both.
Why deal with it now?
Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next. Resealing while only the sealant has failed keeps the job small.
What your quote should include
- Is the sealant right for the movement and the substrate?
- Their approach to joint depth and backing
- Whether their applicators hold CSCS cards
- Their pre-qualification and accreditations
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Make sure contractors see the asbestos survey before cutting out old mastic
- Keep a record of which joints were resealed and when
- Ask fit-out and M&E contractors to report any sealant they disturb
- Put external and wet-area joints on a regular inspection round
Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer. Your maintenance team can look at extract fans at the same time.
A failed external joint lets water in every time it rains. 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.
Why it fails
A split down the middle of the bead tells a different story. Typically the movement was too much for the sealant chosen. The same product in the same joint tends to fail the same way, which is why we look at the joint design as well.
Site and facilities staff are often the first to spot these:
- Wall and floor joints that have lost their seal
- Damp patches where an external joint has failed
- Untidy joints in a reception, shop floor or lobby
- Weathered facade sealant that no longer flexes
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Building owners, agents and FMs in TN21
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Common questions from TN21 clients
What about asbestos in old mastic?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How do we get a quote?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.
Which site documents can you send us?
The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you work for facilities managers and managing agents?
Yes. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.
Will the building have to shut during the work?
We phase the work so parts of the building stay open. Tell us your site hours and access windows and we’ll plan around them.
