Facade sealing across Charlwood

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

Facade sealing for commercial buildings in Charlwood

Facade sealants sit in the sun, rain and frost every day, 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 it fails, the whole bead is cut away and the joint rebuilt. We work on stone and brick facade joints, window and door perimeters and cladding panel joints, and the failures we’re asked to look at most are cladding panel joints that have opened up and leaks at window and door perimeters. Facilities teams, main contractors and managing agents in Charlwood tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In the countryside around places like Charlwood, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Why act early in Charlwood

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. Older rural buildings around Charlwood move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Sites and facades in and around Charlwood

A number of hotels sit less than 2 miles from Charlwood. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. Charlwood lies roughly 24 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

For contractors at a school such as Charlwood Village Primary School, sealing has to be finished before term starts. Hospital estates such as Farmfield Hospital (psychiatric), 1.3 miles to the north-east of Charlwood, 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.

Charlwood is about 3 miles south-west of Horley, in Surrey. Any commercial site in Charlwood is covered, for single jobs and planned programmes alike. Our Surrey coverage takes in 379 places, large and small. Sites around Brighton have their own page, roughly 23 miles from Charlwood.

Honest limits

Honesty saves time and money. New sealant won’t cure:

  • Water getting in through cracked render or porous masonry
  • Providing access systems for the work
  • Installing or repairing glazing systems

If in doubt, ring 01277 525 020 or email us and we’ll say what we think before you book.

Where we work in Charlwood

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

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

What affects the price in Charlwood

A fixed quote reflects the actual work. It allows for:

  • Location, for remote and island sites
  • How accessible the joints are
  • Phasing around occupants
  • The product specified

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

What we need to price the job

However big the job, the same details help:

  • The asbestos register, for older buildings
  • Anything awkward about access or site hours
  • The site address and postcode
  • Specification clauses that apply

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or email us.

Do you need facade sealing in Charlwood?

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.

Site and facilities staff are often the first to spot these:

  • Unsightly perimeter sealant on a visible elevation
  • Failed seals around shopfront and entrance frames
  • Damp patches beside frames after rain
  • Air leaks through failed facade joints

Hotel extensions and refits, at places such as Stanhill Court Hotel, which lies north-west of Charlwood, typically run between busy periods, so the sealing is squeezed into short windows.

Choosing a commercial sealant contractor

Your questions answered

Is Charlwood off your patch?

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

Can you take on a job at a hospital such as Farmfield Hospital (psychiatric)?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Is any job too small?

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

Which sealant do you use on facades?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

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.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
