Facade sealing near Leigh

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

What we are called out for in Leigh

Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.

What tends to prompt an enquiry:

  • Unsightly perimeter sealant on a visible elevation
  • Failed sealant on precast panel joints
  • Old perimeter mastic that has dried out
  • Perimeter joints where frames meet the structure

For a contractor working at a hospital such as Hollanden Park Hospital (2.2 miles north-east of Leigh), perimeter and facade sealing is planned around patients and deliveries.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • Health and safety accreditation such as CHAS
  • The named product and why it was chosen
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

Facade sealing in Leigh, done properly

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. If you are dealing with patch repairs that keep failing and failed seals around shopfront and entrance frames, we can help. Most enquiries from Leigh start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

For a site near Leigh, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.

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 are clear about what is covered before work starts.

Doing it in-house

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Work for main contractors and building owners

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Leigh can form part of a wider programme.

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Common questions from Leigh clients

Is Leigh too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you take on a job at a hospital such as Hollanden Park Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months.

Can you work in cold or wet weather?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, and we build that into the programme.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Facades, frames and programmes in Leigh

Leigh is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. Leigh is about 25 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

For contractors at a school such as Leigh Primary School, sealing has to be finished before term starts. Historic houses such as Penshurst Place, 2 miles south-west of Leigh, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Leigh is about 3 miles west of Tonbridge, in Kent. Looking for facade sealing in Leigh? We can help, as we do across Kent. Leigh is one of 931 places we cover in Kent for facade joints. We also cover London, around 25 miles from Leigh.

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Move anything stored against the joints
  • Agree which areas must stay open

Advice

What affects the price in Leigh

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • Whether the work must be split into stages

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • Anything awkward about access or site hours
  • Clear photographs of the problem areas
  • Whether an asbestos survey exists
  • The type of building and who uses it

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or email drawings and photos with what you know.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Damaged frames that need replacing
  • Joints too narrow for the movement they take, which need redesign
  • Damp caused by condensation inside the building

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly.
