Commercial mastic work in Polstead Heath

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, because the duty to manage asbestos sits with the dutyholder. If a material is suspected, work stops until it’s tested, and we don’t remove asbestos-containing materials ourselves. We work on kitchen worktops and splashbacks, washrooms and tea points and floor and threshold joints, and the usual reasons a site gets in touch are weathered facade sealant that no longer flexes and earlier reseals applied straight onto the failed bead. Searching for sealant specialists in Polstead Heath? We have been sealing commercial buildings since 2005.

On a typical commercial building in Polstead Heath, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Work in smaller places such as Polstead Heath tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Our process

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking as long as the agreed scope needs, from a single visit to a programme spread over several weeks. Smaller jobs around Polstead Heath can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Arrange parking or a loading space
  • Tell us which areas need to stay in use

Request a quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Questions we are asked in Polstead Heath

What site paperwork comes with a job in Polstead Heath?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Can you supply sealant in our brand colour for a site in Polstead Heath?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

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.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Quoting for work in Polstead Heath

These are the things that shape the price:

  • Quantities, in metres or numbers
  • Which sealant the job calls for
  • How much existing material needs removing
  • Any access equipment needed

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older
  • Any specification or named product

For a fixed quote, speak to us on 01277 525 020 or email a schedule or drawings. Our quote form is another easy route.

What the job involves on each surface

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.

Shop fronts and retail fit-outs

In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line, frequently colour-matched to the fit-out. We’ll confirm the colours available for the specified product.

Honest limits

We check first that sealant really is the fix. It isn’t the answer for:

  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Structural cracks or movement the joints weren’t designed for

If you’re not sure, just call 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Joints and surfaces we work on

  • Window and door perimeters
  • External facade joints
  • Floor and threshold joints
  • Kitchen worktops and splashbacks
  • Movement joints in walls and floors
  • Washrooms and tea points

Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
