Mastic sealing for Broomfield sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Mastic sealing in Broomfield

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. If you have damp patches beside frames and old repairs sealed over failed mastic, we can put it right, on shopfronts below residential blocks, external wall and movement joints and communal entrances and stairwells alike. A single leaking joint is often how a building in Broomfield first comes to us: we look at the rest while we are there and tell you what we find.

In a smaller place such as Broomfield, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Broomfield can sit alongside others in a wider programme across Essex.

Common problems we fix in Broomfield

The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

These are often picked up first by site or facilities staff:

  • Cracked, hardened mastic round windows on a block
  • Damaged joints in communal entrances and corridors
  • Estate-wide sealant that is simply worn out
  • Water getting in round frames after rain

Owners of student blocks near Anglia Ruskin University (2.1 miles south of Broomfield) can schedule frame and external mastic for the summer vacation.

What your quote should include

  • Health and safety accreditation such as CHAS
  • How they’ll work around occupants
  • Proof of insurance
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

Keeping the joints sound

Once the work is signed off, these steps help:

  • Ask residents or tenants to report leaks and draughts early
  • Start inspections with the most exposed faces
  • Plan resealing building by building rather than complaint by complaint
  • Protect low-level joints in entrances

Where a paintable product was specified, it can be painted after curing. Silicone usually can’t be painted, so keep decorators off it.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

FAQs: Broomfield

Does your area include sites such as Regiment Business Park, near Broomfield?

Yes. We cover Broomfield and the area around it, including industrial estates, business parks and retail parks such as Regiment Business Park. Send details of the unit and the work through our quote form for a quick quote.

Will you take on a block within reach of Beaulieu Park station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.

Do you do block-wide mastic programmes?

We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

How many days will you need on site?

That varies with the scale of the job, but the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.

Can people stay in the building while you reseal?

We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you cover Broomfield?

Yes. Sites across Broomfield are covered, with one number for every area we cover.

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Any access equipment needed
  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • Backing rod, priming and other preparation

A quote for mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Before you send an enquiry

Diagnosis starts before we arrive. Let us know:

  • What the building is and how it’s used
  • The asbestos register, for older buildings
  • The product your specification calls for
  • Your programme or deadline

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Mastic sealing around Broomfield: points for this area

Blocks of flats and mixed-use buildings often cluster around stations such as Beaulieu Park station, 2.3 miles south-east of Broomfield, and their window and balcony mastic tends to age at the same rate across a building.
