Facade sealing in Beaconsfield

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

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

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.

Facade sealing in Beaconsfield, done properly

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, but not always. We will tell you if we think the leak is coming from somewhere sealant won’t fix. We work on stone and brick facade joints, cladding panel joints and perimeter joints where frames meet the structure, and what we are called in for most is facade joints cracked through the middle and previous reseals run over old sealant. One point of contact handles commercial sealant work in Beaconsfield from the first photos to the final walk-round, whether it’s one building or several.

Many towns of Beaconsfield’s size have older buildings being converted or extended, which puts new frames and panels against old brick, stone or render. Those junctions need a sealant and primer that suit both surfaces.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Can work at a site such as Buckinghamshire New University fit around teaching?

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Do your applicators hold CSCS cards?

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

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

What will the job cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.

Surface by surface

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Contractors’ notes for Beaconsfield

The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. Beaconsfield lies roughly 25 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

For a contractor working at a hospital such as Chalfonts and Gerrards Cross Hospital, 3.7 miles to the east of Beaconsfield, perimeter and facade sealing is planned around patients and deliveries. For a contractor at a hotel such as Crazy Bear Hotel, 0.7 miles to the south-east of Beaconsfield, the mastic often has to be finished before a reopening date.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

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.

Do you need facade sealing in Beaconsfield?

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.

Things that usually lead to an enquiry:

  • Patch repairs that keep failing
  • Discoloured or dirty facade joints
  • Sealant pulling away from frames or panels
  • Old perimeter mastic that has dried out

New units and refits on sites such as Knave's Beech Retail Park, 2 miles to the west of Beaconsfield, need their panel and perimeter joints sealed to the specification.

What to look for in a quote

  • Is the sealant right for the movement and the substrate?
  • The terms of the workmanship guarantee
  • Will RAMS and insurance details be available?
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Town-centre premises in Beaconsfield may have limited parking, so tell us what’s nearby. On estates and business parks it’s usually simpler.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Arrange parking or a loading space
  • Send your site hours and access windows
  • Tell us which areas need to stay in use

How the quote is worked out

What shapes the price:

  • The site’s rules and procedures
  • Access and working height
  • Which sealant the job calls for
  • How much existing material needs removing

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • When you need the work done
  • Whether an asbestos survey exists
  • Where the site is, with the postcode
  • Clear photographs of the problem areas
