Need facade sealing in Hoppers Corner?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. If others near Hoppers Corner need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full.
  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.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected
  • Share your working hours and any access restrictions

How we handle facade sealing in Hoppers Corner

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. We work on stone and brick facade joints, coping and flashing joints and window and door perimeters, and the failures we are asked to look at most are perimeter joints where frames meet the structure and previous reseals run over old sealant. A single leaking joint is often how a building in Hoppers Corner 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 Hoppers Corner, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, call 01277 525 020 or email the details over and we will arrange a return visit.

Hoppers Corner: questions and answers

Is Tovil Green Business Park, near Hoppers Corner, within your area?

Yes. Estates, retail parks and business parks around Hoppers Corner, Tovil Green Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Is Hoppers Corner too small for you to travel to?

Not at all. Hoppers Corner is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What do you charge?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.

Do you need to see the site first?

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

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

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

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

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

What sets the cost

We price every job individually. The things that drive the figure:

  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages
  • Distance, for remote addresses
  • Backing rod, priming and other preparation

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Details that help us quote

However big the job, these details speed things up:

  • Any specification or named product
  • Clear photos of the problem areas
  • Your programme or deadline
  • The type of building and who uses it

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email us to discuss it first.

Facade sealing in Hoppers Corner: the local picture

Hoppers Corner is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Hoppers Corner is about 29 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

For contractors at a college like MidKent College Maidstone Campus (1.7 miles north-east of Hoppers Corner), perimeters and internal sealant are timed for the holidays. For contractors on a campus like University for the Creative Arts - Maidstone, which lies north-east of Hoppers Corner, facade and perimeter sealing has to fit around students and term dates. Hospital estates such as Maidstone Hospital (to the north-east of Hoppers Corner) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Hoppers Corner is about 3 miles west of Maidstone, in Kent. We cover commercial sites throughout Hoppers Corner, whether it’s a single job or part of a planned programme. Hoppers Corner is one of 931 places in Kent on our list. Sites around London have their own page, about 29 miles away.

Surface by surface

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone.

Site staff or a sealant specialist?

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Cracked or spalling substrates that need repair before sealing
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Replacing glass or failed glazing units

If you’re not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer.

Surfaces we seal

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

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Check the asbestos register before old mastic is disturbed
  • Avoid harsh cleaners on facade sealant
  • Add perimeter sealant to planned maintenance checks
  • Record the product and colour used on each elevation

After heavy weather, check vulnerable elevations for signs of water inside. An early report normally means a small reseal rather than a bigger repair.

Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.
