Facade sealing across Horton

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What happens if it’s left?

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. One visit to deal with every failing joint makes more sense than several trips to a place like Horton, rather than one at a time. Send photographs of each area and we will quote for the lot.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

  • Fixed quotes based on photos, drawings or a visit

How we handle facade sealing in Horton

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 cold air coming in at window perimeters and facade joints cracked through the middle, across stone and brick facade joints, shopfront frames and perimeter joints where frames meet the structure. Looking for mastic applicators who cover Horton? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

For a site near Horton, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we will quote to suit.

Work we carry out in Surrey comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email drawings and photos and we’ll come back to it.

Mastic packages on Horton sites

The area within 2 miles of Horton holds several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. Horton is about 13 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

For a contractor working at a hospital such as West Park Hospital, 0.8 miles south-west of Horton, perimeter and facade sealing is planned around patients and deliveries. New units and refits on sites such as Barwell Business Park, 0.9 miles to the west of Horton, need their panel and perimeter joints sealed to the specification. Work at a hotel such as Chessington Safari Hotel, 1.1 miles to the west of Horton, tends to be programmed around bookings, mastic included.

General trades versus a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Horton can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We plan access and the order of elevations with the client.
  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. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Explain the parking and delivery arrangements
  • Tell us which areas need to stay in use
  • Share your working hours and any access restrictions

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Cracked or spalling substrates that need repair before sealing
  • Joints too narrow for the movement they take, which need redesign
  • Providing access systems for the work

If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think.

What we seal

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

What the job involves on each 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 we will mention any edges that need repair.

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.

What sets the cost

Quotes vary with the job. It mainly depends on:

  • Access and working height
  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages
  • The size and state of each joint

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Asbestos survey details if the building is older
  • Where the site is, with the postcode
  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or send photos by email.

Questions about Horton

Can work at a site such as University for the Creative Arts fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you work on a hospital site such as West Park Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Do you hold CHAS accreditation?

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

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.

Can the sealant be colour-matched?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Can you look at water coming in around a frame?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we will tell you which.
