Commercial sealant contractors for businesses in Blean

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

How we handle commercial sealant contractors in Blean

Sealant joints are easy to overlook until one lets water in. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors looking after property in Blean. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on window and door perimeters, kitchen worktops and splashbacks and movement joints in walls and floors, and the failures we’re asked to look at most are external beads that have gone brittle and cracked and gaps behind commercial kitchen worktops and sinks. Facilities teams, main contractors and managing agents in Blean tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

If you look after more than one building near Blean, the work can be planned as one programme, so standards and paperwork match across every site.

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

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If others near Blean need work, visits can be combined. You will have a fixed quote before work starts.

  1. We start with the evidence: photos, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  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

  • Send your site hours and access windows
  • Share the asbestos register for older buildings
  • Warn occupants and staff about the work

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Advice

Owners, agents and contractors

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.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Blean can form part of a wider programme.

What we can’t put right

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

  • A dripping trap, valve or pipe behind a fitting
  • Roof leaks that only look like a joint problem
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

If you’re not sure, just ring 01277 525 020 or email us and we will give you a straight answer.

What we seal

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

Your questions answered

Can the sealant on our Blean premises match the finishes?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.

Will you take on work at estates like John Roberts Business Park, close to Blean?

Yes. We cover Blean and the area around it, including industrial estates, business parks and retail parks such as John Roberts Business Park. Photos and a short description are enough for a first look.

Do you work in Blean?

Yes. Blean is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or email a schedule or drawings.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How is commercial sealant work priced?

Start with whatever information is to hand. Questions or a site visit follow where needed, then a fixed quote.

Do you hold CHAS accreditation?

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

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

What we’re called out for in Blean

External sealant takes a steady beating from the weather. Sunny elevations dry the surface out and exposed ones take driving rain. Once it stiffens, the joint opens up at the next big temperature swing.

It’s worth sending us details if you spot any of the following:

  • A top-up bead over failed sealant, now lifting
  • Damp patches where an external joint has failed
  • Untidy joints in a reception, shop floor or lobby
  • Wall and floor joints that have lost their seal

Sites a few miles apart, such as John Roberts Business Park and Lamberhurst Farm Industrial Estate, can share one programme and one point of contact.

What your quote should include

  • How the joint faces will be prepared and primed
  • The terms of the workmanship guarantee
  • What level of public liability insurance do they hold?
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

Shops, offices and hotels in and around Blean

The South East is one of the drier parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. Central London is about 51 miles from Blean. Business parks and retail centres are common around the capital’s motorway corridors. Firms with branches across the South East can use one contractor for every site.

Premises within reach of Canterbury West station, 2.1 miles south-east of Blean, often have busy frontages where joints are seen by everyone passing. In a retail centre such as Whitefriars Shopping Centre, 2.6 miles south-east of Blean, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.

Blean is about 3 miles north-west of Canterbury, in Kent. We send applicators to Blean for sealant joints, handled exactly as we handle every other area. Our Kent coverage takes in 931 places, large and small. Sites around London have their own page, roughly 51 miles from Blean.

Why deal with it now?

Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. Halls, stores and units around places like Blean may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
