About our facade sealing in Tokers Green

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. The enquiries we see most involve previous reseals run over old sealant and discoloured or dirty facade joints, on stone and brick facade joints, window and door perimeters and coping and flashing joints. Facilities teams, main contractors and managing agents in Tokers Green tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Tokers Green, 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 behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Commercial clients in Tokers Green

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.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Tokers Green. Several sites can go on one quote, which keeps the paperwork simple.

What we can’t put right

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Cracked or spalling substrates that need repair before sealing
  • Providing access systems for the work
  • Damp caused by condensation inside the building

If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think.

Joints and surfaces we work on

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

Facades, frames and programmes in Tokers Green

Tokers Green sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Tokers Green is about 39 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

New units and refits on sites such as Oxford Road Business Park, 2.2 miles to the south-west of Tokers Green, need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as Spire Dunedin Hospital (3 miles south of Tokers Green), perimeter and facade sealing is planned around patients and deliveries.

What we’re called out for in Tokers Green

Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

What tends to prompt an enquiry:

  • Discoloured or dirty facade joints
  • Water coming in around window frames
  • Perimeter sealant that has split or peeled away
  • Cladding panel joints that have opened up

For contractors at a school such as Kidmore End Church of England Primary School, sealing has to be finished before term starts.

What to look for in a quote

  • How they’ll work around occupants
  • Whether old or failed sealant will be cut out, not overlaid
  • How long is the guarantee, and what does it include?
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

Questions we’re asked in Tokers Green

Can you work around term dates at a campus such as University of Reading?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is hospital work, at somewhere like Spire Dunedin Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Do you hold CHAS accreditation?

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

Can you work in cold or wet weather?

Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated.

Can you send site paperwork?

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

Can you handle several sites?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Tokers Green, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Warn occupants and staff about the work
  • Tell us which areas need to stay in use
  • Send any specification or drawings in advance

Doing it in-house

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Why deal with it now?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Converted and older buildings near places like Tokers Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
