Mastic sealing for Dyer's End sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What we are called out for in Dyer's End

Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

Common reasons buildings call us in:

  • Estate-wide sealant that is simply worn out
  • Old repairs sealed over failed mastic
  • Repeated reactive repairs to the same buildings
  • Window mastic that has split and shrunk

If you own or manage units on a site such as Hunnable Industrial Estate (2.4 miles east of Dyer's End), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

What to look for in a quote

  • Whether old or failed sealant will be cut out, not overlaid
  • Who will actually carry out the work
  • Are they CHAS accredited or on Constructionline?
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Mastic sealing for commercial buildings in Dyer's End

In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you have worn sealant at communal door frames and patchy repairs in mismatched sealant, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Dyer's End tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Rural conversions near places like Dyer's End often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

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

Different surfaces, different methods

Tenement and older buildings

Some old mastics in pre-2000 buildings contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.

External movement joints

Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Share the asbestos register when you send details
  • Group repairs into a planned programme
  • Prioritise elevations facing the weather
  • Log resealing dates block by block

Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.

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

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For a building around Dyer's End, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. First comes a look at the joints and, for older buildings, the asbestos records.

Advice

Leave it or put it right?

Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. Around Dyer's End, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • Constructionline member for supplier checks
  • Colour agreed before work starts
  • A range of standard colours, depending on the product
  • One number for every site we cover

Questions about Dyer's End

Is Dyer's End too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Will you price a mastic programme across our Dyer's End portfolio?

Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.

Can you send RAMS and CSCS details before starting?

Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you work for managing agents and housing associations?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

For owners and agents in Dyer's End

At about 44 miles from central London, Dyer's End is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.

Older buildings near Dyer's End, from historic houses such as Hedingham Castle, 4.4 miles to the south-east of Dyer's End, to more modest stock, need compatible products when frames are resealed. If you’re responsible for a building such as Parish Church of St Peter and St Thomas, frame and door mastic needs the same attention as any other property.
