Facade sealing for businesses in Bedmond

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Maintenance after handover

A few simple habits keep the new joints working:

  • Investigate damp beside windows promptly
  • Confirm the survey covers external sealants in older buildings
  • Note when each elevation was last resealed
  • Insist on a full cut-out when joints are renewed

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.

Facade sealing for commercial buildings in Bedmond

Managing agents and owners in Bedmond ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. If you’re dealing with damp patches beside frames after rain and perimeter sealant that has split or peeled away, we can put it right, on coping and flashing joints, shopfront frames and cladding panel joints alike. A single leaking joint is often how a building in Bedmond 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.

For a site near Bedmond, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.

We sign every job 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

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

What sets the cost

Before we quote, we look at:

  • Whether the work must be split into stages
  • How much there is to seal
  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants

No two sites price the same: 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

It doesn’t need to be a full survey. These details are enough to start:

  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • Where the site is, with the postcode
  • Whether the building will be occupied during the work

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email a schedule or drawings.

What happens if it’s left?

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. One visit to deal with every failing joint makes more sense than several trips to a place like Bedmond, rather than one at a time. Photos of every joint help us quote for the whole job.

A quote for facade joints depends on quantities, condition and access. Ask us for a fixed quote.

Why us?

  • Joints cleaned back to sound surfaces
  • Sealing commercial buildings since 2005
  • CHAS accredited
  • 12-month guarantee on workmanship

Our process

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking anything from a single day to several weeks, depending on joint lengths, access and the weather. For a building around Bedmond, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  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. Failed beads are removed in full.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Share your working hours and any access restrictions
  • Make sure the joints can be reached
  • Agree which areas must stay open

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

New build and refits around Bedmond

Bedmond lies roughly 20 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. Bedmond is in the South East, one of the UK’s drier regions. 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.

For a contractor working at a hospital such as Leavesden Hospital (1.3 miles south of Bedmond), perimeter and facade sealing is planned around patients and deliveries. With historic properties like High Elms Manor (1.5 miles south-east of Bedmond) in the area, refurbishment work often meets old masonry that needs compatible sealants.
