About our mastic sealing in Crays Hill

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. Site teams most often ask us about a mix of products and colours from past repairs and no planned programme for sealant, on communal entrances and stairwells, window and door perimeters on blocks and communal kitchens and washrooms. Searching for sealant specialists in Crays Hill? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

For buildings around smaller places like Crays Hill, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Crays Hill: questions and answers

Do you cover business parks and estates near Crays Hill, such as Mayflower Retail Park?

Yes. Our area takes in Crays Hill and its surroundings, with estates and business parks such as Mayflower Retail Park included. Send details of the unit and the work through our quote form for a quick quote.

We manage a building near Wickford station. Can you help?

Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

What if the old mastic contains asbestos?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

Can you reseal a whole block or estate?

Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.

What paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.

Can you seal joints high up on a block?

Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Substrate edges that need repairing first
  • Misted or failed double-glazed units
  • Frames that are rotten, warped or broken

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly.

What we seal

  • Shopfronts below residential blocks
  • Balcony and threshold joints
  • External wall and movement joints
  • Window and door perimeters on blocks
  • Communal kitchens and washrooms
  • Communal entrances and stairwells

Commercial clients in Crays Hill

Building owners and managing agents use us on everything from one building to a spread of sites around Crays Hill. One quote can cover more than one site, so there’s one set of paperwork to deal with.

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. We can agree access arrangements and keyholder contacts beforehand.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Crays Hill can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First we look at the mastic on each building and note what needs replacing.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Getting the site ready

  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs

Get a fixed quote

Send us photos, 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.

Frames, entrances and external joints in Crays Hill

Crays Hill lies roughly 25 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.

Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Site managers at schools like Crays Hill Primary School can fit frame mastic into the summer works. Landlords with units on estates such as Mayflower Retail Park (to the south of Crays Hill) can bring frame, door and external mastic across several units into one programme.

Crays Hill is about 2 miles north of Basildon, in Essex. We send applicators to Crays Hill for mastic joints, handled exactly as we handle every other area. We work across 644 places in Essex, from busy centres to rural villages. Sites around London have their own page, about 25 miles away.

When to bring in 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.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What the job involves on each surface

Communal areas

Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Fresh joints make shared areas look looked after.

Planned maintenance

Adding mastic to planned maintenance avoids reactive repairs and spreads the work.

How the quote is worked out

Before we quote, we look at:

  • Any access equipment needed
  • Location, for remote and island sites
  • Site requirements such as inductions and permits
  • The size and state of each joint

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Details that help us quote

However big the job, these details speed things up:

  • Your programme or deadline
  • Whether the building will be occupied during the work
  • The asbestos register, for older buildings
  • The product your specification calls for

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or send photos by email.
