Construction mastic in Bocking's Elm, done properly

External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work so it helps to sequence elevations with some flexibility. Internal areas can typically carry on while the outside waits. We work on sanitary and kitchen joints, floor and skirting junctions and internal decorators’ caulk, and the failures we are asked to look at most are caulk cracking where joints are moving more than expected and early adhesion failures on new external joints. Whoever orders the work in Bocking's Elm, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

On a small site around Bocking's Elm, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.

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

Honest limits

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

  • Oversized gaps that need packing or adjustment by others
  • Joints damaged after sign-off by following trades
  • Specifying the product where the designer hasn’t

If you’re not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer.

What we seal

  • Window and door perimeters
  • Floor and skirting junctions
  • Sanitary and kitchen joints
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Brick and block movement joints

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Signs you need construction mastic in Bocking's Elm

Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with. Better to raise it at the start than seal a joint that’s bound to fail.

Most enquiries start with something like this:

  • Existing joints on a refurb that need cutting out and resealing
  • New external sealant already peeling away
  • Mastic snags holding up handover
  • Window and door perimeters that won’t pass inspection

Projects at schools like St Clare's Catholic Primary School work to term dates, so mastic is programmed tightly.

What your quote should include

  • Their plan for phasing and protecting the area
  • How joint depth will be controlled
  • What site paperwork they can supply
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

What affects the price in Bocking's Elm

These are the things that shape the price:

  • Site requirements such as inductions and permits
  • Distance, for remote addresses
  • Quantities, in metres or numbers
  • Whether the work must be split into stages

The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • Whether the building will be occupied during the work
  • When you need the work done
  • Clear photographs of the problem areas
  • Where the site is, with the postcode

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send photos by email.

Bocking's Elm: questions and answers

Is Newman Industrial Estate, near Bocking's Elm, within your area?

Yes, sites like Newman Industrial Estate are within our area, along with the rest of Bocking's Elm. Photos and a short description are enough for a first look.

Can you work around term dates at a campus such as Adult Community College Clacton?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you install fire-rated sealant as part of a package?

Fire-rated sealing at service penetrations and linear gaps can be included where specified. Tell us what records you need and we will confirm with the quote.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Does weather affect external mastic work?

External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work.

Why deal with it now?

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. One mastic subcontractor for the lot keeps it simple, with the same standard on every plot. Small buildings around Bocking's Elm suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

  • A Constructionline member, so easy to vet
  • Sealing commercial buildings since 2005
  • Matching to RAL references, product permitting
