What Barham’s businesses ask us to seal

The 3 miles around Barham take in at least three named trading estates, business parks or retail parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen, often in a colour the occupier specifies. Barham has a number of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading.

Sites a few miles apart, such as Barham Business Park and CT3 Business Park, can share one programme and one point of contact. For tenants and agents on sites such as Barham Business Park, 1.5 miles south of Barham, office fit-outs, reception joints and window perimeters are the usual sealant work. Premises within reach of Snowdown station, 2.4 miles east of Barham, often have busy frontages where joints are seen by everyone passing.

How we handle commercial sealant contractors in Barham

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested (removing asbestos-containing materials isn’t something we do). If you’re dealing with layers of sealant, all of them failing and mouldy silicone around WCs, urinals and vanity tops, we can help, on kitchen worktops and splashbacks, washrooms and tea points and window and door perimeters alike. For commercial sealant work in Barham, you deal with one contact from quote to sign-off, whether it’s one building or several.

If you look after more than one building near Barham, the work can be planned as one programme, with one quote format and one point of contact.

Commercial sealant work around smaller places like Barham 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. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Barham. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Why act early in Barham

A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. Often the fitting is sound and the joint is the only thing letting it down. A careful reseal is a far smaller undertaking than replacement, and we will say so if the frame or fitting is life-expired. Converted and older buildings near places like Barham tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Barham may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with the evidence: photographs, drawings or a look on site.
  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. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Preparing the site

  • Let us know about inductions and permits
  • Point out parking and an unloading spot
  • Move anything stored against the joints

Quotes

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

What the job involves on each surface

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price, and we’ll confirm the colours available for the specified product.

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Keep barriers up until the new sealant has cured
  • Act on the first lifting edges rather than waiting
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Brief cleaning contractors to avoid scourers and blades on sealant

Let your cleaning contractor know what’s new. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces, while a neutral cleaner and a soft cloth do no harm.

Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.

Questions about Barham

Is Barham too far out for you?

Not at all. Barham is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Will our hotel in Barham need to close for the work?

Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.

Will you just go over the old 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.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

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 long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Will the building have to shut 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.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
