Construction mastic for businesses in Canterbury

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

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. For premises in central Canterbury, deliveries and parking need a bit of planning, whereas edge-of-town units normally have yard space. Let us know what’s there when you send details.

  1. We start with the drawings, specification and programme.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  4. Each area is sealed when it’s released.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. After snagging, the work is handed over under our 12-month guarantee.

Getting the site ready

  • Agree which areas must stay open
  • Tell staff and tenants when we’ll be in
  • Send any specification or drawings in advance

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

About our construction mastic in Canterbury

Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, and we are fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on floor and skirting junctions, brick and block movement joints and cladding and panel joints, and what we are called in for most is sanitary sealant damaged by following trades and frame perimeters left unsealed or poorly sealed. Facilities teams, main contractors and managing agents in Canterbury tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Places the size of Canterbury tend to see a steady run of new-build and refurbishment schemes. For main contractors and developers, the mastic package covers window and door perimeters, facade and cladding joints, and internal sealant where it’s specified.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

General trades versus a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Different surfaces, different methods

Snagging before handover

The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area and damaged joints are redone rather than patched.

Fire-rated sealant where specified

Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps so we’ll flag where the detail needs something different. Record requirements are agreed with the quote.

Keeping the joints sound

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

  • Ask installers to correct oversized gaps first
  • Note which sealant went where at handover
  • Ask cleaners to use soft cloths around fresh sealant
  • Brief following trades on areas that have been sealed

If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit, priced as part of the package or separately.

One unsealed frame can let water into finished internal areas. That typically means redoing finishes in a completed area and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.

Quoting for work in Canterbury

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • Induction, permit and paperwork requirements
  • Location, for remote and island sites

A quote for mastic packages depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

What to include in your enquiry

To price the job accurately, we need to understand the site. Send us:

  • The site address and postcode
  • What the building is and how it’s used
  • How the joints are reached, and at what height
  • The product your specification calls for

For a fixed quote, call the office on 01277 525 020 or email a schedule or drawings. You can also send details through our quote form.

Building and refurbishing in Canterbury

At about 53 miles from central London, Canterbury is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.

Work at a hotel such as Cathedral Gate Hotel, less than half a mile west of Canterbury, tends to be programmed around bookings, mastic included. On a campus such as University of the Creative Arts, which lies south-east of Canterbury, new teaching buildings and residences are usually built and refurbished around the academic year. Extensions at sites like Kent and Canterbury Hospital, 0.9 miles to the south of Canterbury, normally sit beside working departments, and the mastic follows strict access rules.

Canterbury is in Kent. Businesses, contractors and managing agents in Canterbury use us for work on mastic packages, as part of our coverage of Kent. Canterbury is one of 931 places in Kent on our list. We also cover London, around 53 miles from Canterbury.

Business premises anywhere in CT1, CT2, CT4 and CT3 are within our area. Streets here include Long Market, High Street and High Street St Gregorys, and sites on any of them can send details for a fixed quote.

If your building is just outside Canterbury, we cover Wincheap (1 mile south-west), Harbledown (1 mile west), Hales Place (1 mile north), Thanington (1 mile south-west) and Stuppington (1 mile south). Further afield, our area takes in Ashford (13 miles south-west), Margate (15 miles north-east), Dover (14 miles south-east), Folkestone (14 miles south), Ramsgate (15 miles east) and Whitstable (6 miles north-west). Among the larger centres in Kent is Canterbury, and we take on mastic packages for its commercial and public buildings.

Why it’s worth doing now in Canterbury

Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification rather than at the snagging stage. Called in at the end, the same issues surface during handover. On a busy site in a large place like Canterbury, a failed joint gets worse with every day of use. Acting early keeps it a sealant job.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why appoint us

  • Work carried out by CSCS-carded applicators
  • Fixed quotes based on photos, drawings or a visit

FAQs: Canterbury

Will you plan work around the academic year at somewhere like University of the Creative Arts?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you cover business parks and estates near Canterbury, such as Wincheap Industrial Estate?

Yes. We cover Canterbury and the area around it, including industrial estates, business parks and retail parks such as Wincheap Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Can you work to our specification?

We work to the specification and the manufacturer’s installation guidance. Preparation, backing and depth follow the product guidance.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.
