Mastic sealing in Penpont, done properly

Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. We work on communal entrances and stairwells, communal kitchens and washrooms and window and door perimeters on blocks, and what we’re called in for most is worn sealant at communal door frames and open joints in brickwork or panels. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Penpont, that means joint design, primers and backing rod as standard.

Travel to smaller places like Penpont is planned so several buildings can be done on one trip. Send addresses and photos for a quote covering the batch.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Our process

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For work around Penpont, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Preparing the site

  • Send your site hours and access windows
  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work

Request a quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Why act early in Penpont

Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. For buildings near Penpont, dealing with all the failing joints at once saves return trips. Send photos and we will quote for everything together.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

  • A range of standard colours, depending on the product
  • Constructionline member

Surface by surface

Communal areas

Low-level communal joints get damaged more than most, so they often need renewing sooner.

Window and door perimeters on blocks

Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. We’ll confirm the colours available for the specified product.

How the quote is worked out

Before we quote, we look at:

  • Working within restricted access windows
  • Specialist products, such as fire-rated or hygienic sealants
  • Backing rod, priming and other preparation
  • Distance, for remote addresses

A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Drawings or a marked-up plan, if available
  • How the joints are reached, and at what height
  • Specification clauses that apply
  • Whether the building will be occupied during the work

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or send photos by email to discuss it first.

When it isn’t the sealant
