How we handle commercial sealant contractors in Bricket Wood

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. We work on kitchen worktops and splashbacks, movement joints in walls and floors and window and door perimeters, and what we’re called in for most is damp patches where an external joint has failed and shrunken sealant along kitchen worktops and splashbacks. A specialist sealant contractor works differently from a general builder: on jobs in Bricket Wood, preparation and product choice get the time they need.

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

Small businesses near places like Bricket Wood frequently occupy converted farm buildings. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.

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.

Leave it or put it right?

A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. In many cases the element is fine and only the seal around it has given up. Resealing usually costs far less than renewal. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

How the quote is worked out

These are the things that shape the price:

  • Joint width, depth and condition
  • Which sealant the job calls for
  • How accessible the joints are
  • The total length or number of joints

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Before you send an enquiry

A good diagnosis starts with the right details. Let us know:

  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings
  • The postcode of the building
  • Access details, including height

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Diagnose, treat, sign off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Several jobs near Bricket Wood can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. We start with the evidence: photos, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  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.

What we need from you

  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000
  • Tell us your opening times and when work is allowed

Bricket Wood: questions and answers

Will our hotel in Bricket Wood need to close for the work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Will you take on work at estates like Colne Way Industrial Estate, close to Bricket Wood?

Yes. Our area takes in Bricket Wood and its surroundings, with estates and business parks such as Colne Way Industrial Estate included. Photos and a short description are enough for a first look.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

How is commercial sealant work priced?

Photos, drawings or a schedule of the joints are normally enough to start through our quote form. If a visit is needed we will book one, and a fixed quote follows.

What guarantee do you give on resealing?

The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.

Do you check for asbestos before removing sealant?

It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

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

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think.

Surfaces we seal

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

Do you need commercial sealant contractors in Bricket Wood?

Plenty of failed joints were never sealed with the right product. 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.

Common reasons buildings call us in:

  • Expansion joints with the sealant torn out
  • Black mould through washroom sealant that won’t clean off
  • Window and door perimeter joints that have cracked open
  • Leaks that seem to come through a sealant line

Offices and shops close to stations such as Bricket Wood station, 0.5 miles east of Bricket Wood, tend to be busy all day, so sealant work is planned around opening hours.

  • What the guarantee covers, and for how long
  • How they handle RAMS and site documents
