Facade sealing for businesses in East Farleigh

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

Building owners, agents and FMs in East Farleigh

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in East Farleigh can sit alongside others in a wider programme across Kent.

Facade sealing in East Farleigh, done properly

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. We work on perimeter joints where frames meet the structure, stone and brick facade joints and coping and flashing joints, and the failures we are asked to look at most are damp patches beside frames after rain and old perimeter mastic that has dried out. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in East Farleigh, that means joint design, primers and backing rod as standard.

Construction in and around smaller places such as East Farleigh is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

New build and refits around East Farleigh

East Farleigh sits in one of the drier corners of the country, the South East. 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. There are several hotels within about 2 miles of East Farleigh. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

For a contractor working at a hospital such as Maidstone Hospital, 1.5 miles north of East Farleigh, perimeter and facade sealing is planned around patients and deliveries. For a contractor at a hotel such as Grange Park Hotel, which lies north-east of East Farleigh, the mastic often has to be finished before a reopening date.

East Farleigh is about 2 miles south-west of Maidstone, in Kent. We cover commercial sites throughout East Farleigh. Our Kent coverage takes in 931 places, large and small. Sites around London have their own page, roughly 30 miles from East Farleigh.

Your questions answered

Is East Farleigh too small for you to travel to?

No. Places such as East Farleigh are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Will you plan work around the academic year at somewhere like University for the Creative Arts - Maidstone?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Do you provide access for facade work?

That varies with the building and the access on offer. When you ring 01277 525 020 or email a schedule or drawings, describe the access.

Who decides which product is used?

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

Why act early in East Farleigh

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. Older rural buildings around East Farleigh move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Pricing facade joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

What you get with us

  • Joints cleaned back to sound surfaces
  • Standard and matched colours in many product ranges
  • Colours confirmed for the specified product
  • 12-month guarantee on workmanship

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Check that rainwater leaves the facade the way it was designed to
  • Combine resealing with other works that need access
  • Don’t wait for a second leak before calling
  • Never let anyone seal over old sealant

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade instead of soaking the joints.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

When to call us in East Farleigh

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.

Typical triggers for a call:

  • Draughts around frames and panels
  • Old perimeter mastic that has dried out
  • Unsightly perimeter sealant on a visible elevation
  • Water coming in around window frames

When a college such as MidKent College Maidstone Campus, 1.3 miles to the north of East Farleigh, builds or refurbishes, the mastic package normally has to fit around students and staff.

Before you book anyone

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their pre-qualification and accreditations
  • Who will actually carry out the work
  • How they handle RAMS and site documents

Our contractor checklist

How the job changes by surface

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported.

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If others near East Farleigh need work, visits can be combined. 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. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies 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

  • Confirm the product named in the specification
  • Tell us which areas need to stay in use
  • Move anything stored against the joints
