Common questions from Eastbury clients

What site paperwork comes with a job in Eastbury?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Is Eastbury too small for you to travel to?

No. Places such as Eastbury are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

What guarantee do you give on resealing?

The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.

Can areas stay open during the work?

It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance, until its cure time has passed.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How is commercial sealant work priced?

Photos, drawings or a schedule of the joints are usually enough to start through the quote form on this site. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.

Is it OK to apply fresh sealant over existing beads?

Every failed bead is cut out completely. New sealant can’t grip the old bead, so laying over it never lasts, and the faces are brought back to sound, dry material before resealing.

How we handle commercial sealant contractors in Eastbury

Inside a commercial building, sealant does a lot of quiet work: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Outside, it closes facade joints, frame perimeters and movement joints against the weather. We deal with internal and external sealant joints alike, picking the product for each location rather than one tube for everything. If you’re dealing with untidy joints in a reception, shop floor or lobby and external beads that have gone brittle and cracked, we can help, whatever the surface. A single leaking joint is often how a building in Eastbury first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Quotes for commercial sealant in Eastbury can come from photographs and a joint schedule, or from a walk-round, and the scope is set out in writing.

Commercial sealant work around smaller places like Eastbury tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Add sealant to the planned maintenance inspection list
  • Report cracked or peeling sealant early
  • Look at the sealant around anything that has been moved or replaced
  • Ask cleaners to use a soft cloth and mild cleaner on sealant

Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.

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.

What we’re called out for in Eastbury

When a bead peels cleanly off one face, it has failed in adhesion. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. It’s one of the commonest faults we find on earlier work.

Look out for the following:

  • Movement joints packed with grit and debris
  • Greasy, split joints in a kitchen or tea point
  • Window and door perimeter joints that have cracked open
  • Sanitary sealant that has gone black and patchy

For premises around Eastbury where the joint is seen, colour options for the product are confirmed with the quote.

What your quote should include

  • Whether old or failed sealant will be cut out, not overlaid
  • What the guarantee covers, and for how long
  • Will CSCS-carded applicators be on site?
  • What site paperwork they can supply

How to choose a sealant contractor

When something else is needed

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Water from a services leak rather than a joint
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

If in doubt, speak to us on 01277 525 020 or use the quote form and we’ll say what we think.

What we seal

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

How a job runs

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Eastbury, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. You send photographs, drawings or a list of the joints and areas involved, or we arrange a site visit.
  2. Next comes a diagnosis and a fixed quote.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Getting the site ready

  • Flag any permit to work we’ll need
  • Arrange parking or a loading space
  • For older buildings, check the asbestos register before work

Different surfaces, different methods

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, frequently colour-matched to the fit-out. We’ll confirm the colours available for the specified product.

Washrooms and toilets

Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead, room by room if that suits the building.
