Cox Green: questions and answers

Can you work on a hospital site such as St Mark's Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you work around term dates at a campus such as Berkshire College of Agriculture?

Yes. Education sites typically 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.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you provide access for facade work?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions.

Do you cover Cox Green?

Yes. We cover Cox Green, and you can ring 01277 525 020 or email the details over to get started.

Will rain stop the work?

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

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

About our facade sealing in Cox Green

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. We work on stone and brick facade joints, shopfront frames and coping and flashing joints, and what we’re called in for most is failed seals around shopfront and entrance frames and weathered facade joints that have lost their grip. Looking for mastic applicators who cover Cox Green? We have been sealing commercial buildings since 2005.

Conversions around smaller places like Cox Green often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.

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

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Facades, frames and programmes in Cox Green

Several hotels sit less than 2 miles from Cox Green. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.

Extensions at sites like St Mark's Hospital (1.2 miles north of Cox Green) typically sit beside working departments, and the mastic follows strict access rules. When a college such as Berkshire College of Agriculture (3 miles north-west of Cox Green) builds or refurbishes, the mastic package usually has to fit around students and staff. Projects at schools like Wessex Primary School work to term dates, so mastic is programmed tightly.

Why it’s worth doing now in Cox Green

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. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

A quote for facade joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

Why us?

  • Over 20 years of commercial sealing
  • Specification-led, product-correct work
  • Work carried out by CSCS-carded applicators
  • A Constructionline member, so easy to vet

Different surfaces, different methods

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Insist on a full cut-out when joints are renewed
  • Report water ingress at frames as soon as it shows
  • Inspect facade joints on a regular cycle
  • Keep pressure washers away from fresh sealant

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

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Honest limits

Some faults sit outside our scope, and we say so rather than covering them up:

  • Providing access systems for the work
  • Damaged frames that need replacing
  • Installing or repairing glazing systems

If you are not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer.

What we seal

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