Facade sealing for businesses in Sutton

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

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Render or concrete edges that have broken away
  • Arranging specialist high-level access, which is planned with the client
  • Joints whose design needs changing by the specifier

If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Where we work in Sutton

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

Facade sealing for commercial buildings in Sutton

External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. 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. Site teams most often ask us about cladding panel joints that have opened up and discoloured or dirty facade joints, across cladding panel joints, shopfront frames and coping and flashing joints. Facilities teams, main contractors and managing agents in Sutton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Construction in and around smaller places such as Sutton is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Questions about Sutton

Is Sutton off your patch?

Not at all. Sutton is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Would you work within a site like Wellesley Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Sutton need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and the joint faces cleaned.
  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. The finished joints are checked with you.

Getting the site ready

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Check the asbestos register before old mastic is disturbed
  • Avoid patch repairs on failed facade joints
  • Share access with other external trades
  • Record the product and colour used on each elevation

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade instead of soaking the joints.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Common problems we fix in Sutton

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained and tears as the joint moves.

Most enquiries start with something like this:

  • Failed sealant on precast panel joints
  • Staining on stone next to old sealant
  • Patch repairs that keep failing
  • Water coming in around window frames

Units on estates such as Purdey's industrial estate, 0.5 miles north of Sutton, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Questions to ask before you book

  • Their approach to joint depth and backing
  • Is the sealant right for the movement and the substrate?
  • Whether old or failed sealant will be cut out, not overlaid
  • Their public liability cover

Choosing a commercial sealant contractor

Building and refurbishing in Sutton

Sutton lies within about 3 miles of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. At about 35 miles from central London, Sutton is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

For a contractor at a hotel such as The Kings Head Hotel, 1 mile north-west of Sutton, the mastic often has to be finished before a reopening date. For a contractor working at a hospital such as Wellesley Hospital, 1.2 miles south of Sutton, perimeter and facade sealing is planned around patients and deliveries.

Sutton is about 2 miles south-east of Rochford, in Essex. We cover Sutton, with the same fixed quotes and 12-month guarantee as everywhere else. Sutton is one of 644 places in Essex on our list. London is covered too, around 35 miles from Sutton.

We take on facade joints across the SS4 and SS2 postcode area, for business premises of every kind. For a building on Shopland Road, Fleethall Road and Brook Close or nearby, send details and we will quote for facade joints. Close to Sutton, our area also takes in Prittlewell (2 miles south-west), Great Stambridge (2 miles north-east), Stonebridge (2 miles east), Southchurch (2 miles south) and Barling (3 miles east). Nearby towns on our patch include Chelmsford (15 miles north-west), Basildon (11 miles west), Maldon (11 miles north), Canvey Island (7 miles south-west), Billericay (13 miles west) and Rayleigh (5 miles west).

Around Sutton

In Sutton, that means premises near Horse and Groom pub, Garon Park and Cecil Jones College. For rail, the closest station is Southend Airport station, about 0.7 miles west. Nearby you’ll also find Southend University Hospital (1.9 miles south-west) and Rayleigh Windmill Museum (1 mile north-west). For a walk, there’s Lion Creek and Lower Raypits.

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
