Commercial sealant contractors in Balls Cross

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Smaller jobs around Balls Cross can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. You send photographs, drawings or a list of the joints and areas involved.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Before anything is cut out, we agree access, timings and sequence.
  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. Each area is inspected, signed off and backed by our 12-month guarantee.

Getting the site ready

  • Share the asbestos register for older buildings
  • Warn occupants and staff about the work
  • Agree which areas must stay open

Ask for a quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Advice

Commercial sealant contractors in Balls Cross, done properly

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and on a working site that usually surfaces as a leak, a stain or a complaint from occupiers. We are commercial sealant applicators for FMs, managing agents, landlords and contractors looking after property in Balls Cross. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. If you have mouldy silicone around WCs, urinals and vanity tops and leaks that seem to come through a sealant line, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Balls Cross, preparation and product choice get the time they need.

A lot of what we do in Balls Cross is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

In and around smaller places such as Balls Cross, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

What we can’t put right

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Roof leaks that only look like a joint problem
  • Suspect materials that need testing and specialist removal
  • Misted, cracked or failed glazing units (a glazier’s job)

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think before you book.

Surfaces we seal

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

Quoting for work in Balls Cross

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Removal of failed or old sealant
  • Whether the work must be split into stages
  • Quantities, in metres or numbers
  • Which sealant the job calls for

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • The product your specification calls for
  • Your programme or deadline
  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Questions we are asked in Balls Cross

Is a smaller place like Balls Cross outside your area?

Not at all: smaller places are covered as well as 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.

Can the sealant on our Balls Cross premises match the finishes?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we’ll price the work to it.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

How is commercial sealant work priced?

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

After the work

Once the work is signed off, a little attention goes a long way:

  • Deal with small splits before they become leaks
  • Don’t let cleaning or traffic back on before the cure time is up
  • Add sealant to the planned maintenance inspection list
  • 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 failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Sites like these see regular refits, with shopfronts, offices and staff areas to seal, often in a colour the occupier specifies.

A business with units at Colhook Industrial Park. And Hampers Common Industrial Estate needn’t use two contractors for its sealant.

Do you need commercial sealant contractors in Balls Cross?

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.

Any of the following is a good reason to get the joints checked over:

  • Messy, uneven beads from earlier work that let the building down
  • External beads that have gone brittle and cracked
  • Shrunken sealant along kitchen worktops and splashbacks
  • Expansion joints with the sealant torn out

On estates like Colhook Industrial Park. (1.4 miles west of Balls Cross), the office and welfare end of each unit has its own sealant to maintain.
