Commercial sealant contractors near Chobham

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

Commercial sealant contractors in Chobham, done properly

How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. If you are dealing with black mould through washroom sealant that won’t clean off and leaks that seem to come through a sealant line, we can put it right, on movement joints in walls and floors, floor and threshold joints and window and door perimeters alike. A single leaking joint is often how a building in Chobham first comes to us: we look at the rest while we’re there and tell you what we find.

The most common commercial job in Chobham is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Places like Chobham tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. They’re not big jobs one by one, but their joints need the same preparation as anywhere.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Common questions from Chobham clients

Is Chobham Business Centre, near Chobham, within your area?

Yes. We cover Chobham and the area around it, including industrial estates, business parks and retail parks such as Chobham Business Centre. Photos and a short description are enough for a first look.

Is Chobham too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

What site paperwork can you provide?

We confirm documents at quote stage: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Is failed sealant stripped out, or sealed over?

Full removal is part of every quote. Sealing over traps water and lifts once the joint moves.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

What do you need from us to quote?

Photos, drawings or a schedule of the joints are usually 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.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Suspect materials that need testing and specialist removal
  • Cracking that needs a structural engineer to look at it

Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly.

What we seal

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

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

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.

Cost factors for sealant joints

Each job is priced on its own details. The main factors are:

  • Phasing around occupants
  • Removal of failed or old sealant
  • How much there is to seal
  • Location, for remote and island sites

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

What to include in your enquiry

However big the job, the same details help:

  • The postcode of the building
  • Approximate linear metres or a joint schedule
  • A wide shot and a close-up of the area
  • Whether the building will be occupied during the work

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email the details over.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a job in Chobham, the main thing is a clear picture of the work. A fixed quote follows.

  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. Completed areas are signed off with you under our 12-month guarantee.

Preparing the site

  • Point out any areas we must not close
  • Arrange parking or a loading space

Advice

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Check joints after other trades have worked nearby
  • Log reseals in the O&M or maintenance records
  • Keep abrasive pads and scrapers off resealed joints
  • Deal with small splits before they become leaks

Keep an eye out for other trades after we have gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed and the joint gets left open. Where work has disturbed a joint, just phone 01277 525 020 or email a schedule or drawings for a quote.

Tenants and staff spot black or split sealant quickly. Replacing it on a planned cycle keeps complaints down.

Do you need commercial sealant contractors in Chobham?

The wrong sealant in the wrong place is a common cause of early failure. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.

Look out for the following:

  • Smeared sealant across finishes from a rushed job
  • Movement joints packed with grit and debris
  • Sanitary sealant that has gone black and patchy
  • Weathered facade sealant that no longer flexes

Sites a few miles apart, such as Chobham Business Centre and Goldsworth Park Trading Estate, can share one programme and one point of contact.

What your quote should include

  • How long is the guarantee, and what does it include?
  • How joint depth will be controlled
  • Their plan for phasing and protecting the area
  • Their public liability cover
