Commercial clients in Smeeth

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Smeeth. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Facade sealing in Smeeth

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure on offices, blocks and industrial units. Where sealant is the specified fix, we also take on coping and flashing joints. Site teams most often ask us about facade joints cracked through the middle and previous reseals run over old sealant, across coping and flashing joints, window and door perimeters and stone and brick facade joints. Looking for mastic applicators who cover Smeeth? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Conversions of older rural buildings near smaller places such as Smeeth bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or use the quote form and we will come back to it.

Aftercare for building managers

After handover, a little attention goes a long way:

  • Brief window cleaners about newly sealed joints
  • Clear debris that holds water against joints
  • Confirm the survey covers external sealants in older buildings
  • Record the product and colour used on each elevation

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Smeeth, 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. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached
  • Warn occupants and staff about the work

Why deal with it now?

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once. Around Smeeth, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why clients in Smeeth choose us

  • A range of standard colours, depending on the product
  • CHAS accredited contractor
  • Specification-led, product-correct work
  • Colours chosen to suit frames, cladding or finishes where possible

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Arranging specialist high-level access, which is planned with the client
  • Water getting in through cracked render or porous masonry
  • Joints whose design needs changing by the specifier

Not sure which it is? You can ring 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Where we work in Smeeth

  • Window and door perimeters
  • Shopfront frames
  • Perimeter joints where frames meet the structure
  • Stone and brick facade joints
  • Coping and flashing joints
  • Cladding panel joints

Questions about Smeeth

Is hospital work, at somewhere like William Harvey Hospital (Ashford), something you do?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Smeeth off your patch?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Is the work guaranteed?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

Do we need an asbestos check before resealing?

In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Sites and facades in and around Smeeth

Rainfall across the South East, Smeeth included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. Central London is about 53 miles from Smeeth. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.

With historic properties like Westenhanger Castle (to the south-east of Smeeth) in the area, refurbishment work often meets old masonry that needs compatible sealants. School extensions, at buildings such as Smeeth Community Primary School, usually run to the summer holidays, mastic included. For a contractor working at a hospital such as William Harvey Hospital (Ashford), 2.5 miles to the north-west of Smeeth, perimeter and facade sealing is planned around patients and deliveries.

How the job changes by surface

Cladding panel joints

Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.

Window and door perimeters

Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus, neutral-cure product suits most frame-to-wall joints, tooled to shed water.
