How we handle commercial sealant contractors in Fyfield

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in Fyfield. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. If you’re dealing with shrunken sealant along kitchen worktops and splashbacks and hardened, chalky sealant on south-facing or exposed elevations, we can help, on washrooms and tea points, window and door perimeters and floor and threshold joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Fyfield, preparation and product choice get the time they need.

A lot of what we do in Fyfield is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

A job in a smaller place like Fyfield is normally a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Work we carry out in Oxfordshire comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email us and we’ll arrange a return visit.

Why it’s worth doing now in Fyfield

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement, though we’ll tell you honestly if the element itself is the problem. Older rural buildings around Fyfield move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

Why appoint us

  • Joints cleaned back to sound surfaces
  • Health and safety: CHAS accredited
  • RAL and finish matching where the product range allows
  • Colours confirmed for the specified product

Commercial premises in Fyfield

Central London is about 57 miles from Fyfield. The commuter belt holds a great many offices, retail parks and business parks. Occupiers with several premises in the region tend to prefer one contractor and one point of contact. The South East is one of the drier parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.

If you run an office at a site such as Kingston Business Park (1.1 miles south-west of Fyfield), the sealant at reception desks, tea points and frames ages with each fit-out. Whatever the building in Fyfield, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

On site: what to expect

Occupied buildings need a little choreography. 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. For a building around Fyfield, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  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. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Flag any permit to work we will need
  • Send asbestos survey details if the building is pre-2000

When it isn’t the sealant

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

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Structural cracks or movement the joints weren’t designed for
  • Misted, cracked or failed glazing units (a glazier’s job)

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.

What we seal

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

Keeping the joints sound

Problems stay small when the joints are checked regularly. In particular:

  • Log reseals in the O&M or maintenance records
  • Report cracked or peeling sealant early
  • Respect the cure time before reopening an area
  • Add sealant to the planned maintenance inspection list

Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life.

Sealant installed at the same time usually fails in sequence. A few splits this year normally mean more next year so the whole run is worth inspecting. We will tell you which sealant joints need doing first and which can wait.

How the job changes by surface

Shop fronts and retail fit-outs

In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line, frequently colour-matched to the fit-out. We’ll confirm the colours available for the specified product.

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Your questions answered

Can you supply sealant in our brand colour for a site in Fyfield?

Yes, we can normally get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.

Is Fyfield off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Is failed sealant stripped out, or sealed over?

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

Do you work directly for building managers?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
