How we handle facade sealing in Grazeley

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. We work on stone and brick facade joints, coping and flashing joints and cladding panel joints, and the usual reasons a site gets in touch are patch repairs that keep failing and water coming in around window frames. A single leaking joint is often how a building in Grazeley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Sites around smaller places like Grazeley can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.

A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or email the details over and we will arrange a return visit.

Facade sealing in Grazeley: the local picture

Central London is about 39 miles from Grazeley. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Grazeley is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

On a healthcare site such as Royal Berkshire Hospital, 4 miles north of Grazeley, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors refurbishing units at places like Heron Industrial Estate, which lies south-east of Grazeley, the mastic covers cladding panels, roller-door and window perimeters. Building work at universities like University of Reading - Whiteknights Campus, 3.7 miles to the north-east of Grazeley, is often timed for the summer, mastic included.

Grazeley is about 4 miles south of Reading, in Wokingham. Grazeley sits inside our coverage and the rest of Wokingham, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Wokingham coverage takes in 42 places, from busy centres to rural villages.

Why deal with it now?

Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Around Grazeley, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why clients in Grazeley choose us

  • Old sealant cut out, never sealed over
  • Work to your specification and the manufacturer’s guidance
  • CSCS-carded applicators
  • Public liability insurance in place

Take a look at our cost guide or our accreditations and insurance.

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • How much existing material needs removing
  • Site requirements such as inductions and permits
  • Access and working height
  • The total length or number of joints

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • Anything awkward about access or site hours
  • Any specification or named product
  • Whether the building will be occupied during the work
  • When you need the work done

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Doing it in-house

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Jobs in and around smaller places like Grazeley are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand
  • Make sure the joints can be reached

FAQs: Grazeley

Is Heron Industrial Estate, near Grazeley, within your area?

Yes. Our area takes in Grazeley and its surroundings, with estates and business parks such as Heron Industrial Estate included. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Is Grazeley too small for you to travel to?

Not at all. Grazeley is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. That is what makes the new joint last.

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The dutyholder holds the asbestos register. Suspect material is left alone until it has been tested.

Which sealant do you use on facades?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, depending on the substrate and the specification.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

Commercial clients in Grazeley

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

What the job involves on each surface

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.

Precast concrete panels

Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported before sealing.
