Advice

Construction mastic in Little Dunmow

Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. New and existing joints then get the same preparation. We work on brick and block movement joints, internal decorators’ caulk and cladding and panel joints, and the usual reasons a site gets in touch are early adhesion failures on new external joints and old sealant on a refurbishment that needs stripping before new work. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Little Dunmow, preparation and product choice get the time they need.

On a small site around Little Dunmow, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Facades, frames and programmes in Little Dunmow

Little Dunmow is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. At about 33 miles from central London, Little Dunmow 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.

Units on estates such as Martels Industrial Estate (1.7 miles south-west of Little Dunmow) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. On a healthcare site such as Braintree Community Hospital, 5.4 miles east of Little Dunmow, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Little Dunmow is about 6 miles west of Braintree, in Essex. Little Dunmow sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Essex coverage takes in 644 places, from busy centres to rural villages. London is covered too, around 33 miles from Little Dunmow.

  • Sanitary and kitchen joints

Work for main contractors and building owners

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Your questions answered

Do you cover business parks and estates near Little Dunmow, such as Martels Industrial Estate?

Yes. Estates, retail parks and business parks around Little Dunmow, Martels Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Do you take on work at healthcare sites like Braintree Community Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is the mastic package guaranteed?

Our workmanship carries a 12-month guarantee from sign-off. The guarantee covers our work, not later damage by other trades.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you fit around our working hours?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

How do I request a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.

Can you seal external joints in wet or cold weather?

External mastic depends on conditions: each sealant has a temperature range, and the joint must be dry. We plan external elevations with that in mind.

What affects the price in Little Dunmow

Your fixed quote is built from the real scope. It allows for:

  • Whether the work must be split into stages
  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • Access and working height

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • Any dates the work must fit around
  • The site address and postcode
  • Anything awkward about access or site hours
  • The type of building and who uses it

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email the details over.

Do you need construction mastic in Little Dunmow?

Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.

Clients usually get in touch after noticing one or more of the following:

  • Frame gaps too wide for sealant alone
  • Internal caulk splitting as the building dries out
  • Inconsistent sealant finishes from plot to plot
  • A long mastic snag list close to completion

For contractors at a school such as The Flitch Green Academy, sealing has to be finished before term starts.

What your quote should include

  • How they handle RAMS and site documents
  • The named product and why it was chosen
  • How long is the guarantee, and what does it include?
  • Will CSCS-carded applicators be on site?

Our contractor checklist

Different surfaces, different methods

Bathrooms, en suites and washrooms

On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent, plot by plot or floor by floor.

Window and door perimeters

Internal perimeters are normally sealed with a paintable product where decorating follows. We follow what’s specified with colours matched to the frame where needed.
