Facade sealing in Nalderswood

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Facade sealing for commercial buildings in Nalderswood

External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. Most enquiries involve unsightly perimeter sealant on a visible elevation and patch repairs that keep failing, on cladding panel joints, perimeter joints where frames meet the structure and window and door perimeters. A single leaking joint is often how a building in Nalderswood first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Nalderswood, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. 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. Smaller jobs around Nalderswood can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

Your questions answered

Do you cover business parks and estates near Nalderswood, such as Fontigarry Farm Business Park?

Yes. Our area takes in Nalderswood and its surroundings, with estates and business parks such as Fontigarry Farm Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Is Nalderswood too far out for you?

No. Places such as Nalderswood are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Is colour matching possible?

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

When can you be on site?

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.

Different surfaces, different methods

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair.

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Record the product and colour used on each elevation
  • Check that rainwater leaves the facade the way it was designed to
  • Insist on a full cut-out when joints are renewed
  • Confirm the survey covers external sealants in older buildings

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards with a compatible product.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Building owners, agents and FMs in Nalderswood

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Nalderswood can sit alongside others in a wider programme.

Contractors’ notes for Nalderswood

Nalderswood lies roughly 22 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, Nalderswood 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, so external mastic is timed for workable conditions and agreed with the site manager.

School extensions, at buildings such as Burys Court School, usually run to the summer holidays, mastic included. Hospital estates such as Farmfield Hospital (psychiatric) (to the south-east of Nalderswood) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Nalderswood is about 3 miles west of Horley, in Surrey. We send applicators to Nalderswood for facade joints, handled exactly as we handle every other area. Our Surrey coverage takes in 379 places. There’s a separate page for London, about 22 miles away.

Do you need facade sealing in Nalderswood?

Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

What tends to prompt an enquiry:

  • Patch repairs that keep failing
  • Hard, chalky sealant that no longer flexes
  • Perimeter joints where frames meet the structure
  • Air leaks through failed facade joints

When units on a site such as Fontigarry Farm Business Park, 1.9 miles east of Nalderswood, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
