Facade sealing in Saunderton Lee

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

How we handle facade sealing in Saunderton Lee

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Site teams most often ask us about cladding panel joints that have opened up and perimeter joints where frames meet the structure, on shopfront frames, perimeter joints where frames meet the structure and window and door perimeters. Most enquiries from Saunderton Lee start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In the countryside around places like Saunderton Lee, 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 usually 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 are upfront about that.

Common questions from Saunderton Lee clients

Can you work at a site such as Crownfield Industrial Estate, by Saunderton Lee?

Yes. Estates, retail parks and business parks around Saunderton Lee, Crownfield Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Is Saunderton Lee too small for you to travel to?

No. Places such as Saunderton Lee are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

What type of sealant goes on window perimeters?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

How the quote is worked out

Before we quote, we look at:

  • Which sealant the job calls for
  • How accessible the joints are
  • The total length or number of joints
  • Induction, permit and paperwork requirements

Pricing facade joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back
  • Your programme or deadline
  • The postcode of the building

For a fixed quote, ring 01277 525 020 or email a schedule or drawings. Our quote form is another easy route.

Contractors’ notes for Saunderton Lee

At about 34 miles from central London, Saunderton Lee is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Saunderton Lee is in the South East, one of the UK’s drier regions. 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.

For a contractor working at a hospital such as The Paddocks Hospital, 2.7 miles north of Saunderton Lee, perimeter and facade sealing is planned around patients and deliveries. For contractors at a school such as St John's Church of England Primary School, sealing has to be finished before term starts.

Common problems we fix in Saunderton Lee

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

Most enquiries start with something like this:

  • Leaks at window and door perimeters
  • Weathered facade joints that have lost their grip
  • Perimeter sealant that has split or peeled away
  • Gaps between rainscreen or cladding panels

Historic houses such as West Wycombe Park House, 3.6 miles south of Saunderton Lee, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Whether primer will be used where the manufacturer specifies it
  • How they handle RAMS and site documents
  • The named product and why it was chosen

Questions to ask before you appoint anyone

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Why it’s worth doing now in Saunderton Lee

Failed joints let in more than water: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Halls, stores and units around places like Saunderton Lee may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why appoint us

  • Over 20 years of commercial sealing
  • Workmanship guaranteed for 12 months
  • RAL and finish matching where the product range allows
  • Failed material removed, not covered up

Read what affects the cost and how we’re accredited.

Different surfaces, different methods

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.

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. The rod limits depth, leaving the bead able to flex.
