About our facade sealing in Saint Hill Green

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on coping and flashing joints, stone and brick facade joints and shopfront frames, and what we’re called in for most is weathered facade joints that have lost their grip and staining on stone next to old sealant. One point of contact handles commercial sealant work in Saint Hill Green from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Construction in and around smaller places such as Saint Hill Green is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Mastic packages on Saint Hill Green sites

Rainfall across the South East, Saint Hill Green included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Several hotels sit less than 2 miles from Saint Hill Green. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

For contractors at a school such as The Meads Primary School, sealing has to be finished before term starts. Historic houses such as Saint Hill Manor (0.1 miles north-west of Saint Hill Green) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Joints whose design needs changing by the specifier
  • Specialist high-level access methods
  • Damaged frames that need replacing

If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer.

Where we work in Saint Hill Green

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

Different surfaces, different methods

Precast concrete panels

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

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.

Site staff or a sealant specialist?

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What we are called out for in Saint Hill Green

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.

Common reasons buildings call us in:

  • New sealant peeling off old mastic
  • Leaks at window and door perimeters
  • Weathered joints at frame-to-structure perimeters
  • Weathered facade joints that have lost their grip

New wings at hospitals like Queen Victoria Hospital (to the north-east of Saint Hill Green) bring long runs of window and panel joints to seal.

What your quote should include

  • What level of public liability insurance do they hold?
  • Which product they’ll use, and why it suits the joint
  • Whether old or failed sealant will be cut out, not overlaid
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

FAQs: Saint Hill Green

Can you work on a hospital site such as Queen Victoria Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Is Saint Hill Green off your patch?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

How is access to upper-level joints handled?

That varies with the building and the access on offer. Share what access exists or is planned when you send details, and we will agree the approach together.

When can you be on site?

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

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
