Commercial sealant contractors for Grange Park sites

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

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Keep barriers up until the new sealant has cured
  • Keep washroom and kitchen extraction working
  • Keep a record of which joints were resealed and when
  • Keep abrasive pads and scrapers off resealed joints

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are.

Commercial sealant contractors in Grange Park

If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Grange Park, the quickest start is to phone 01277 525 020 or email us with a list of addresses. If you have water staining near frames, panels or ceilings and shrunken sealant along kitchen worktops and splashbacks, we can put it right. Most enquiries from Grange Park start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Multi-site clients with buildings in and around Grange Park can put several sites on one programme, so standards and paperwork match across every site.

For managing agents and FMs looking after premises in Grange Park, access is normally the first question: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.

Every job we finish is backed by a 12-month workmanship guarantee, in Grange Park as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Your questions answered

Do you work in London buildings with loading restrictions?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Does your area include sites such as Colosseum Retail Park, near Grange Park?

Yes. Estates, retail parks and business parks around Grange Park, Colosseum Retail Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Do you work for facilities managers and managing agents?

Yes. A large share of our work comes through facilities managers, managing agents and landlords. Tell us how you issue work and we will fit in.

Is your work guaranteed?

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

Could the old sealant in an older building contain asbestos?

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. HSE guidance on asbestos is a useful reference.

From enquiry to sign-off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes a few hours for one area, or a planned series of visits across a bigger building. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  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. 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

  • Tell staff and tenants when we’ll be in
  • Move anything stored against the joints
  • Have the specification and drawings to hand

Common problems we fix in Grange Park

Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath so it soon peels and traps moisture against the joint. Getting back to a clean joint then means removing every layer.

These are often picked up first by site or facilities staff:

  • Frame mastic that has hardened and come away from the wall
  • Expansion joints with the sealant torn out
  • Black mould through washroom sealant that won’t clean off
  • Greasy, split joints in a kitchen or tea point

Access in Grange Park needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple.

Questions to ask before you book

  • How they handle RAMS and site documents
  • How the existing material will be dealt with
  • Proof of insurance
  • What the guarantee covers, and for how long

How to choose a sealant contractor

How the job changes by surface

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.

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it.

Work for main contractors and building owners

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Grange Park can sit alongside others in a wider programme.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

How the quote is worked out

Before we quote, we look at:

  • Backing rod, priming and other preparation
  • The product specified
  • Distance, for remote addresses
  • Induction, permit and paperwork requirements

A quote for sealant joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

What to include in your enquiry

We can often quote from photos and a few details. Please tell us:

  • Anything awkward about access or site hours
  • Specification clauses that apply
  • Whether the building will be occupied during the work
  • A wide shot and a close-up of the area

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or use the quote form if you’d rather talk the job through.
