Need commercial sealant contractors in Felsted?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Shops, offices and hotels in and around Felsted

At least three named trading, business or retail sites lie within about 3 miles of Felsted. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies. Rainfall across the South East, Felsted included, is lower than in many parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.

Occupiers with premises at both Martels Industrial Estate and Oak Industrial Estate could have the sealant at each handled under one quote.

Sealant applicators in Felsted

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. If you have smeared sealant across finishes from a rushed job and gaps behind commercial kitchen worktops and sinks, we can put it right, whatever the surface. Whoever orders the work in Felsted, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

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

A job in a smaller place like Felsted 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.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Felsted: questions and answers

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

Yes, we can usually get close to most finishes from the product’s colour range. Send colour references or photographs and we will confirm what’s available for the product.

Is a smaller place like Felsted outside your area?

No. Places such as Felsted are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

How do you choose the sealant?

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.

Is the old sealant taken out first?

Removal of the failed sealant is always part of the job. New sealant can’t grip the old bead, so laying over it never lasts; the faces are then cleaned and prepared.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

General trades versus a specialist

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.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Why it’s worth doing now in Felsted

A cheaper quote sometimes means the old bead stays in. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation, because that’s what makes the new bead last. Older rural buildings around Felsted move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Why appoint us

  • 12 months’ guarantee on every job
  • A Constructionline member, so easy to vet
  • Old sealant cut out, never sealed over
  • Matching to RAL references, product permitting

Building owners, agents and FMs in Felsted

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Our process

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes anything from part of a day on a short run of joints to several weeks on a large phased package, and we clear our waste as we work. For a building around Felsted, 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. We start with the evidence: photos, 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. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Make sure the joints can be reached
  • Tell us your opening times and when work is allowed
  • Share the asbestos register for older buildings

Related advice

When to call us in Felsted

When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.

Clients usually get in touch after noticing something like this:

  • Black mould through washroom sealant that won’t clean off
  • Frame mastic that has hardened and come away from the wall
  • Layers of sealant, all of them failing
  • Shrunken sealant along kitchen worktops and splashbacks

A unit on an estate like Martels Industrial Estate, 2.5 miles west of Felsted, normally has an office front, a trade counter and staff facilities with joints of their own.

What to look for in a quote

  • Will RAMS and insurance details be available?
  • How they’ll work around occupants
  • What the guarantee covers, and for how long
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Choosing a commercial sealant contractor

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Faulty windows rather than failed perimeter sealant
  • A dripping trap, valve or pipe behind a fitting
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Surfaces we seal

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