Questions about Easton

Is Easton too far out for you?

No. Places such as Easton are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Which documents can you supply for work in Easton?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Can one contractor look after sealant on all our buildings?

Yes, across South East England, Greater London and all of Scotland. Each site gets the same process and a single contact.

Is the old sealant taken out first?

Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away, so it isn’t something we do.

Can areas stay open during the work?

We phase the work so parts of the building stay open. Tell us your site hours and access windows and we will plan around them.

Does commercial sealant work come with a guarantee?

Each job sits under our 12-month guarantee, starting at sign-off. Looking after the joints as we advise helps them last.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Commercial sealant contractors in Easton

We have applied sealant on commercial sites for over 20 years: 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. Site teams most often ask us about hardened, chalky sealant on south-facing or exposed elevations and frame mastic that has hardened and come away from the wall, across washrooms and tea points, movement joints in walls and floors and window and door perimeters. A single leaking joint is often how a building in Easton first comes to us: we look at the rest while we’re there and tell you what we find.

We price commercial jobs in Easton from photographs, drawings or a site visit, with the scope listed so everyone knows what’s included.

Business units in the countryside around places like Easton are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Different surfaces, different methods

Commercial kitchens and tea points

Gaps and ragged beads trap dirt that cleaning can’t reach, which matters when environmental health officers look at a kitchen. We seal to a neat, cleanable finish and work around service times you agree with us.

Window and door perimeters

Inside, cracked sealant around frames and window boards is common. The product depends on whether the joint will be painted, matched to the frame colour where colour matters.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Walls or slabs moving more than any sealant can take
  • Old mastic that tests positive for asbestos
  • Roof leaks that only look like a joint problem

If in doubt, phone 01277 525 020 or email the details over and we will say what we think before you book.

What we seal

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

Should maintenance staff do it?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

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.

Common problems we fix in Easton

A split down the middle of the bead tells a different story. That typically means the joint stretched further than the product could cope with. Replacing it like for like rarely holds, which is why we look at the joint design as well.

It’s worth sending us details if you spot any of the following:

  • Window and door perimeter joints that have cracked open
  • Sanitary sealant that has gone black and patchy
  • Shrunken sealant along kitchen worktops and splashbacks
  • External beads that have gone brittle and cracked

Whatever the building in Easton, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Before you book anyone

  • Proof of insurance
  • Whether primer will be used where the manufacturer specifies it
  • Are they CHAS accredited or on Constructionline?
  • Is the sealant right for the movement and the substrate?

Our contractor checklist

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a building around Easton, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Tell us which areas need to stay in use
  • For older buildings, check the asbestos register before work
  • Clear stock, furniture or equipment away from the joints

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.
