Facade sealing across Hare Street

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

Facade sealing for commercial buildings in Hare Street

External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range. We build that into the programme and tell you if the forecast changes the plan. Site teams most often ask us about sealant pulling away from frames or panels and cold air coming in at window perimeters, across perimeter joints where frames meet the structure, shopfront frames and cladding panel joints. One point of contact handles commercial sealant work in Hare Street from the first photos to the final walk-round, whether it’s one building or several.

For a site near Hare Street, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

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.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Don’t wait for a second leak before calling
  • Share access with other external trades
  • Inspect facade joints on a regular cycle
  • Insist on a full cut-out when joints are renewed

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.

Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Hare Street, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Tell staff and tenants when we will be in
  • Point out parking and an unloading spot
  • Point out any areas we must not close

Why it’s worth doing now in Hare Street

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure, often turning up far from the joint. One visit to deal with every failing joint makes more sense than several trips to a place like Hare Street, rather than one at a time. Photos of every joint help us quote for the whole job.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why clients in Hare Street choose us

  • Work to your specification and the manufacturer’s guidance
  • 12 months’ guarantee on every job
  • A range of standard colours, depending on the product
  • Over 20 years of commercial sealing

Work for main contractors and building owners

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.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

New build and refits around Hare Street

The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. At about 18 miles from central London, Hare Street is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

Units on estates such as Hallsford Bridge Industrial Estate (to the north-east of Hare Street) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Extensions at sites like Suttons Manor Hospital, 2 miles to the south-west of Hare Street, normally sit beside working departments, and the mastic follows strict access rules. With historic properties like Hill Hall (to the west of Hare Street) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Hare Street is about 5 miles north-west of Brentwood, in Essex. Hare Street sits inside our coverage and the rest of Essex, with the same fixed quotes and 12-month guarantee as everywhere else. Our Essex coverage takes in 644 places, large and small. London is covered too, some 18 miles away.

Questions about Hare Street

Can you take on a job at a hospital such as Suttons Manor Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is Hare Street off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Which sealant do you use on facades?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.

Do we need an asbestos check before resealing?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.

Will you check whether the sealant is causing the leak?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one.

What sets the cost

Quotes vary with the job. Expect it to depend on:

  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation
  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

Before you send an enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • When you need the work done
  • Any specification or named product
  • Clear photographs of the problem areas
  • Rough lengths or quantities, or drawings if you have them

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
