Commercial sealant contractors in Selsfield Common, done properly

If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Selsfield Common, the quickest start is to call the office on 01277 525 020 or email us with a list of addresses. The enquiries we see most involve damp patches where an external joint has failed and hardened, chalky sealant on south-facing or exposed elevations, across window and door perimeters, external facade joints and kitchen worktops and splashbacks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Selsfield Common it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

Business units in the countryside around places like Selsfield Common are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why deal with it now?

Leaving a failed joint rarely saves money. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below, which brings decorators and flooring contractors into the repair. Dealing with it while the damage stops at the bead is the cheaper route. One visit to deal with every failing joint makes more sense than several trips to a place like Selsfield Common. Photos of every joint help us quote for the whole job.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • A fixed quote before work starts
  • CHAS accredited contractor
  • 12 months’ guarantee on every job
  • Failed material removed, not covered up

See our cost guide or how we’re accredited.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Have extract fans checked so wet areas dry out
  • Check joints after other trades have worked nearby
  • Keep barriers up until the new sealant has cured
  • Add sealant to the planned maintenance inspection list

Let your cleaning contractor know what’s new. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces; a mild cleaner is all most joints need.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to.

When to call us in Selsfield Common

Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. On a busy commercial site several of those pile up at once, which is why regular inspection pays.

Things that usually lead to an enquiry:

  • Window and door perimeter joints that have cracked open
  • Wall and floor joints that have lost their seal
  • Hardened, chalky sealant on south-facing or exposed elevations
  • Gaps behind commercial kitchen worktops and sinks

If you run an office at a site such as Rowfant Business Centre, 1.8 miles to the north-west of Selsfield Common, the sealant at reception desks, tea points and frames ages with each fit-out.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Their pre-qualification and accreditations
  • Will CSCS-carded applicators be on site?
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Suspect materials that need testing and specialist removal
  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Roof leaks that only look like a joint problem

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Where we work in Selsfield Common

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Selsfield Common can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. We strip the failed bead and prepare both faces of the joint.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Flag any permit to work we’ll need
  • Let building users know which areas are affected

Your questions answered

Is Selsfield Common off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will our hotel in Selsfield Common need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

Are you CHAS accredited and on Constructionline?

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

Is the old sealant taken out first?

Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Does commercial sealant work come with a guarantee?

It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.

Which site documents can you send us?

Send your site requirements with the enquiry. From you, we will need the asbestos information for older buildings and any site rules.

Different surfaces, different methods

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. The design and sign-off of fire stopping belong to the designer and building control; we install what’s specified.

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 will confirm the colours available for the specified product.
