Commercial sealant contractors across SL4: what to expect

Mastic Doctor has been sealing joints for businesses and contractors since 2005: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on movement joints in walls and floors, window and door perimeters and washrooms and tea points, and the usual reasons a site gets in touch are messy, uneven beads from earlier work that let the building down and weathered facade sealant that no longer flexes.

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  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. 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.

Shops, offices and hotels in SL4

Commercial buildings across SL4 range from older premises altered many times to recent units on business parks. Each building needs the right product for its surfaces, from stone and brick to coated aluminium and laminate.

We work across Greater London and the South East counties, so jobs in SL4 are planned with access, loading and parking in mind.

Windsor: Shops and cafés around stations like Windsor & Eton Central station, 1 mile to the north-east of Windsor, trade from early, so work is timed around them. Refits at hotels like Clarence Hotel, 0.5 miles to the north-east of Windsor, bring joints at vanity tops, bars and reception desks that guests see every day.

Looking after the joints

For the best life from the joints:

  • Don’t let cleaning or traffic back on before the cure time is up
  • Look at the sealant around anything that has been moved or replaced
  • Report cracked or peeling sealant early
  • Brief cleaning contractors to avoid scourers and blades on sealant

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.

In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are, so sound, smooth joints matter.

Different surfaces, different methods

Shop fronts and retail fit-outs

Shop fits put sealant right in front of customers. Joints around counters, displays and shopfront frames have to look tidy as well as seal. We’ll confirm the colours available for the specified product.

Fire-rated seals where specified

Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services, and we will tell you if the detail calls for something else.

Building owners, agents and FMs in SL4

Building owners and managing agents use us on everything from one building to a spread of sites around SL4. Several sites can go on one quote, which keeps the paperwork simple.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Why it fails

No sealant joint is permanent. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. In commercial buildings those factors tend to act together, so periodic inspection matters more than any date on a schedule.

Any of the following is a good reason to get the joints checked over:

  • Expansion joints with the sealant torn out
  • Earlier reseals applied straight onto the failed bead
  • Window and door perimeter joints that have cracked open
  • Smeared sealant across finishes from a rushed job

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Water from a services leak rather than a joint
  • Structural cracks or movement the joints weren’t designed for
  • A failed roof covering or waterproofing membrane

Questions we are asked in SL4

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Who decides which product is used?

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.

How is commercial sealant work priced?

The main factors are metres of joint, removal, access, the product and how many phases there are. For a fixed quote, send details through our quote form.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Can one contractor look after sealant on all our buildings?

Yes. We regularly take on multi-site work and planned maintenance programmes, quoted per building or as a package.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Which site documents can you send us?

Let us know your requirements when you ask for a price, and the paperwork is confirmed with the quote. From you, we will need the asbestos information for older buildings and any site rules.
