Facade sealing near St Michaels

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

Doing it in-house

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Facade sealing for commercial buildings in St Michaels

Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. The enquiries we see most involve weathered joints at frame-to-structure perimeters and cladding panel joints that have opened up, on window and door perimeters, perimeter joints where frames meet the structure and coping and flashing joints. A single leaking joint is often how a building in St Michaels first comes to us: we look at the rest while we are there and tell you what we find.

In the countryside around places like St Michaels, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Damp caused by condensation inside the building
  • Damaged frames that need replacing
  • Work on the window or framing system itself

If you’re not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer.

Mastic packages on St Michaels sites

Central London is about 45 miles from St Michaels. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.

With historic properties like Smallhythe Place, 3.3 miles to the south of St Michaels, in the area, refurbishment work often meets old masonry that needs compatible sealants. For contractors refurbishing units at places like Business Park, 2 miles west of St Michaels, the mastic covers cladding panels, roller-door and window perimeters. School extensions, at buildings such as St Michael's Church of England Primary School, normally run to the summer holidays, mastic included.

St Michaels is about 8 miles south-west of Ashford, in Kent. St Michaels sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Kent, 931 places are covered, including St Michaels. For work in that direction, see our Brighton page, about 40 miles away.

Commercial sites across TN30 are covered for facade joints. If your site is on Ox Lane, Swain Road and Grange Road or close by, we can quote for facade joints.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Combine resealing with other works that need access
  • Record the product and colour used on each elevation
  • Clear debris that holds water against joints
  • Add perimeter sealant to planned maintenance checks

After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. For work around St Michaels, 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 the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Agree which areas must stay open
  • Tell us what induction or permit system the site runs

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Advice

St Michaels: questions and answers

Does your area include sites such as Business Park, near St Michaels?

Yes, sites like Business Park are within our area, along with the rest of St Michaels. Photos and a short description are enough for a first look.

Is St Michaels off your patch?

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

Can staff carry on working while you’re here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

How many days will you need on site?

That varies with the scale of the job, but the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Is the work guaranteed?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

Surface by surface

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface.

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch without tearing.
