About our commercial sealant contractors in Gatcombe

Pricing a commercial reseal is a short process. Our quote form takes photos, drawings or a schedule of the areas and you can also ring 01277 525 020 or email the details over to talk it through. Where the photographs don’t tell the full story, we arrange a site visit, and a fixed quote for the agreed scope follows. We work on kitchen worktops and splashbacks, external facade joints and washrooms and tea points, and what we are called in for most is expansion joints with the sealant torn out and messy, uneven beads from earlier work that let the building down. A specialist sealant contractor works differently from a general builder: in Gatcombe, that means joint design, primers and backing rod as standard.

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

Business units in the countryside around places like Gatcombe are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • A failed roof covering or waterproofing membrane
  • Faulty windows rather than failed perimeter sealant
  • Water from a services leak rather than a joint

Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly before you book.

What we seal

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

What happens if it’s left?

Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after. Where it helps, we quote a patch and a full reseal side by side. Converted and older buildings near places like Gatcombe tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Why clients in Gatcombe choose us

  • Standard and matched colours in many product ranges

Building owners, agents and FMs in Gatcombe

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Gatcombe, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

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

What we need from you

  • Share the asbestos register for older buildings
  • Confirm the product named in the specification
  • Agree which areas must stay open

Questions about Gatcombe

Can the sealant on our Gatcombe premises match the finishes?

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

Can you work at a site such as Mountjoy Industrial Estate, by Gatcombe?

Yes. We cover Gatcombe and the area around it, including industrial estates, business parks and retail parks such as Mountjoy Industrial Estate. A few photographs and the unit address let us price the work.

Do you check for asbestos before removing sealant?

Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

Does commercial sealant work come with a guarantee?

A 12-month guarantee covers the workmanship. Keeping joints clean and inspected helps them last well beyond that.

Which site documents can you send us?

The paperwork is agreed with the quote: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.

How is commercial sealant work priced?

The main factors are metres of joint, removal, access, the product and how many phases there are. To get a fixed price, send details through our quote form, or phone or email us.

Different surfaces, different methods

Washrooms and toilets

Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal.

Window and door perimeters

The perimeter joint between a frame and the structure keeps rain out of the reveal. 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.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Make sure ventilation in wet areas is switched on and working
  • Check sealant as part of routine building inspections
  • Log reseals in the O&M or maintenance records
  • Report cracked or peeling sealant early

We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.

Sealant installed at the same time normally fails in sequence. A few splits this year usually mean more next year so the whole run is worth inspecting. We will tell you which sealant joints need doing first and which can wait.
