About our facade sealing in Lenham Forstal

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. If you have facade joints cracked through the middle and old perimeter mastic that has dried out, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Lenham Forstal is the same: the right product in a properly prepared joint.

Conversions of older rural buildings near smaller places such as Lenham Forstal bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Why deal with it now?

Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Halls, stores and units around places like Lenham Forstal may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why clients in Lenham Forstal choose us

  • Old sealant cut out, never sealed over
  • A Constructionline member, so easy to vet
  • Matching to RAL references, product permitting
  • Work carried out by CSCS-carded applicators

Take a look at our cost guide and our accreditations and insurance.

Cost factors for facade joints

Each job is priced on its own details. The things that drive the figure:

  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • Site requirements such as inductions and permits
  • The size and state of each joint

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Asbestos survey details if the building is older
  • How the joints are reached, and at what height
  • Any dates the work must fit around
  • Clear photos of the problem areas

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or phone 01277 525 020 or use the quote form if you’d rather talk the job through.

Common problems we fix in Lenham Forstal

New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.

Any of the following is a good reason to get the joints checked over:

  • Failed sealant on precast panel joints
  • Facade joints cracked through the middle
  • Previous reseals run over old sealant
  • Failed seals around shopfront and entrance frames

School extensions, at buildings such as The Lenham School, normally run to the summer holidays, mastic included.

Questions to ask before you appoint anyone

Keeping the joints sound

To get the most from the new sealant:

  • Inspect facade joints on a regular cycle
  • Combine resealing with other works that need access
  • Keep pressure washers away from fresh sealant
  • Don’t wait for a second leak before calling

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and cuts time on site.

From enquiry to sign-off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Lenham Forstal are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Point out any areas we must not close
  • Arrange parking or a loading space
  • Make sure the joints can be reached

Common questions from Lenham Forstal clients

Will you plan work around the academic year at somewhere like Canterbury Christ Church University?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you keep pace with our programme in Lenham Forstal?

Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

How long does a typical visit take?

That varies with the scale of the job, but the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

What do you charge?

Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or send details through our quote form.

Will you check whether the sealant is causing the leak?

Yes. We check the sealant joints and report what we find as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
