Facade sealing for businesses in Horley

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Horley, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Share your working hours and any access restrictions
  • Let building users know which areas are affected

Advice

About our facade sealing in Horley

External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. The enquiries we see most involve failed seals around shopfront and entrance frames and unsightly perimeter sealant on a visible elevation, on shopfront frames, stone and brick facade joints and coping and flashing joints. A specialist sealant contractor works differently from a general builder: on jobs in Horley, preparation and product choice get the time they need.

Conversions of older rural buildings near smaller places such as Horley bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Working within restricted access windows
  • The size and state of each joint
  • Travel to remote or island sites
  • How accessible the joints are

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • A wide shot and a close-up of the area
  • When you need the work done
  • The site address and postcode
  • Rough lengths or quantities, or drawings if you have them

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or send photos by email.

Mastic packages on Horley sites

Rainfall across the South East, Horley included, is lower than in many parts of the UK. 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. Horley is about 69 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.

For contractors refurbishing units at places like Alkerton Oaks Business Park, 2.4 miles west of Horley, the mastic covers cladding panels, roller-door and window perimeters. Hotel extensions and refits, at places such as Wroxton House Hotel (1.3 miles south of Horley), normally run between busy periods, so the sealing is squeezed into short windows.

Horley is about 3 miles north-west of Banbury, in Oxfordshire. Anywhere in OX15, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 423 places across Oxfordshire fall within our area, Horley among them. There’s a separate page for Oxford, roughly 25 miles from Horley.

Anyone looking for facade sealing in OX15 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on Manor Orchard and Little Lane or close by, we can quote for facade joints. Nearby places we also cover include Wroxton (1 mile south), Drayton (2 miles south-east), Neithrop (3 miles south-east) and Ruscote (3 miles south-east) for facade joints. Nearby towns on our patch include Banbury (3 miles south-east), Chipping Norton (12 miles south-west), Grimsbury (4 miles south-east), Bloxham (5 miles south), Bodicote (5 miles south-east) and Upper Heyford (13 miles south-east).

Different surfaces, different methods

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first.

Your questions answered

Is Horley too small for you to travel to?

Not at all: smaller places are covered as well as 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 work at a site such as Wroxton College fit around teaching?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Can you find out why a window is leaking?

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

Do you replace failed glazing units?

No. That work needs a glazing specialist. What we seal are the joints around frames and panels on commercial buildings.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

When to call us in Horley

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

If one of these sounds familiar, it’s time for a closer look:

  • Damp patches beside frames after rain
  • Sealant pulling away from frames or panels
  • Previous reseals run over old sealant
  • Failed seals around shopfront and entrance frames

For a contractor working at a hospital such as Horton General Hospital, 3.6 miles to the south-east of Horley, perimeter and facade sealing is planned around patients and deliveries.

What your quote should include

  • Who will actually carry out the work
  • The terms of the workmanship guarantee
  • Whether primer will be used where the manufacturer specifies it
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Why act early in Horley

Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. One visit to deal with every failing joint makes more sense than several trips to a place like Horley. Photos of every joint help us quote for the whole job.

Access can matter as much as the joints themselves: 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.

Why appoint us

  • CHAS accredited contractor
  • One phone line for London, the South East and Scotland
  • Failed material removed, not covered up
  • 12 months’ guarantee on every job

Doing it in-house

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
