About our commercial sealant contractors in Brook

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. We are commercial sealant applicators for FMs, managing agents, landlords and contractors with sites in Brook. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. If you have weathered facade sealant that no longer flexes and earlier reseals applied straight onto the failed bead, we can put it right. A specialist sealant contractor works differently from a general builder: in Brook, that means joint design, primers and backing rod as standard.

Quotes for commercial sealant in Brook can come from photos and a joint schedule, or from a walk-round, and the scope is set out in writing.

Work in smaller places such as Brook tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Your questions answered

Is a smaller place like Brook outside your area?

No. Places such as Brook are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Do hotels near Brook have to close for sealant work?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

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 and isn’t worth paying for.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

What guarantee do you give on resealing?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

What about asbestos in old mastic?

It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested.

Common problems we fix in Brook

A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath. By the time it shows, there can be two or three layers to cut out.

Common reasons buildings call us in:

  • Window and door perimeter joints that have cracked open
  • A top-up bead over failed sealant, now lifting
  • Mouldy silicone around WCs, urinals and vanity tops
  • Gaps behind commercial kitchen worktops and sinks

A hotel such as The Bartley Lodge Hotel, 1.4 miles to the east of Brook, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

How to choose a sealant contractor

What sets the cost

The price varies from site to site. Expect it to depend on:

  • Site requirements such as inductions and permits
  • The size and state of each joint
  • Access and working height
  • Phasing around occupants

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • When you need the work done
  • Specification clauses that apply
  • How the joints are reached, and at what height
  • Rough lengths or quantities, or drawings if you have them

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email a schedule or drawings.

What happens if it’s left?

Some managers wait for a fit-out before touching the mastic. That’s reasonable for internal joints that are just tired-looking, but external and wet-area joints that already leak shouldn’t wait. Splitting the scope into now and later is often the sensible compromise. One visit to deal with every failing joint makes more sense than several trips to a place like Brook. Send photographs of each area and we will quote for the lot.

Pricing sealant joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Why us?

  • Constructionline member for supplier checks
  • Fixed quotes based on photos, drawings or a visit
  • CHAS accredited contractor
  • Work carried out by CSCS-carded applicators

Maintenance after handover

For the best life from the joints:

  • Check joints after other trades have worked nearby
  • Have extract fans checked so wet areas dry out
  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Note dates and locations of sealant work for future planning

Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them. Where work has disturbed a joint, just give us a call on 01277 525 020 or send details through our quote form for a quote.

Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Brook are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First, details come to us: photos, drawings or a schedule of the areas.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. We strip the failed bead and prepare both faces of the joint.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Preparing the site

  • Flag any permit to work we’ll need
  • Make sure the joints can be reached
  • Send any specification or drawings in advance

Advice

What the job involves on each surface

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. We will recommend the right filler or sealant for the traffic and movement, and tell you if the edges need repairing first.

Washrooms and toilets

Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.

Shops and cafés around stations like Ashurst New Forest station, 4.2 miles to the south-east of Brook, trade from early, so work is timed around them.
