Mastic sealing across Hyde farm estate

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What happens if it’s left?

Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee. Failed sealant in a building in Hyde farm estate can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Why appoint us

  • Commercial sealant work since 2005
  • Standard and matched colours in many product ranges
  • Failed material removed, not covered up
  • Our applicators hold CSCS cards

Mastic sealing in Hyde farm estate

There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable. We will confirm the colours available for the specified product. The enquiries we see most involve a mix of products and colours from past repairs and open joints in brickwork or panels, on shopfronts below residential blocks, external wall and movement joints and communal kitchens and washrooms. For commercial sealant work in Hyde farm estate, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Across Greater London, Hyde farm estate included, the ULEZ applies, and parking and loading rules differ from street to street. For block-wide work, a place to park and store materials saves time on every visit.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Our process

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. In Hyde farm estate, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

What we need from you

  • Warn occupants and staff about the work
  • Agree which areas must stay open
  • Point out parking and an unloading spot

Getting a fixed quote

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Cost factors for mastic joints

These are the things that shape the price:

  • Access and working height
  • How much there is to seal
  • Backing rod, priming and other preparation
  • Specialist products, such as fire-rated or hygienic sealants

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Sending details for a quote

However big the job, the same details help:

  • Rough lengths or quantities, or drawings if you have them
  • Clear photographs of the problem areas
  • Any specification or named product
  • How the joints are reached, and at what height

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Owners, agents and contractors

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

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

What the job involves on each surface

Planned maintenance

Planned resealing replaces emergency callouts and spreads the work.

Tenement and older buildings

Older mastic can contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.

Common questions from Hyde farm estate clients

Can you work in a care home near Hyde farm estate with residents in?

Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.

We manage a building near Balham 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.

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.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Can you reseal a whole block or estate?

Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee, backed by public liability insurance.

After the work

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Include mastic in your cyclical inspections
  • Make it easy for occupiers to report draughts
  • Track which buildings were done and when
  • Avoid piecemeal callouts where you can

Keep records of when each building was resealed. It helps plan the next round and shows what was done.

Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.
