Facade sealing for commercial buildings in Horseport

A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear. The enquiries we see most involve hard, chalky sealant that no longer flexes and perimeter joints where frames meet the structure, on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure. A specialist sealant contractor works differently from a general builder: on jobs in Horseport, preparation and product choice get the time they need.

Around smaller places like Horseport, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Why it’s worth doing now in Horseport

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Older rural buildings around Horseport move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

FAQs: Horseport

Is Horseport too far out for you?

Not at all. Horseport is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Would you work within a site like Fordingbridge Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Which sealant do you use on facades?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

How many days will you need on site?

That varies with the scale of the job, though a typical visit typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we will set out a timescale with the quote.

Are you CHAS accredited?

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

Contractors’ notes for Horseport

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.

Older buildings in the area around Horseport, such as Breamore House, 3 miles north of Horseport, need care when sealed: the product has to suit soft or historic materials. Work at a hotel such as Greyhound Hotel, less than half a mile north-west of Horseport, tends to be programmed around bookings, mastic included. Extensions at sites like Fordingbridge Hospital (under half a mile west of Horseport) usually sit beside working departments, and the mastic follows strict access rules.

Different surfaces, different methods

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, as the specification sets out.

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’ll mention any edges that need repair.

What affects the price in Horseport

To price the job, we consider:

  • Distance, for remote addresses
  • Site requirements such as inductions and permits
  • The total length or number of joints
  • The product specified

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

What to include in your enquiry

We can often quote from photos and a few details. It helps to include:

  • How the joints are reached, and at what height
  • The type of building and who uses it
  • Photos of the joints, close up and from further back
  • Any specification or named product

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, give us a call on 01277 525 020 or email us.

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Clear debris that holds water against joints
  • Plan facade sealing alongside redecoration
  • Avoid patch repairs on failed facade joints
  • Confirm the survey covers external sealants in older buildings

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.

Coordinate facade sealing with other external works. One set-up for several trades saves money.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Horseport can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Arrange parking or a loading space
  • Confirm the product named in the specification
  • Let us know about inductions and permits
