Mastic sealing for businesses in Stonebridge

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Different surfaces, different methods

Commercial and mixed-use buildings

Mixed-use buildings combine shops below with flats or offices above the programme has to suit everyone. Tell us your site hours and access windows and we will plan around them.

Window and door perimeters on blocks

On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.

About our mastic sealing in Stonebridge

Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. We work on window and door perimeters on blocks, shopfronts below residential blocks and communal kitchens and washrooms, and the usual reasons a site gets in touch are window mastic that has split and shrunk and draughts at frames across a block. Looking for mastic applicators who cover Stonebridge? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

In and around smaller places like Stonebridge, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Stonebridge, 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. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Arrange parking or a loading space
  • Share your working hours and any access restrictions

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or email drawings and photos with what you know.

Why it’s worth doing now in Stonebridge

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. Halls, stores and units around places like Stonebridge may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why clients in Stonebridge choose us

  • Health and safety: CHAS accredited
  • Colours chosen to suit frames, cladding or finishes where possible
  • Coloured sealants to suit the setting, where available
  • CSCS-carded applicators

Common questions from Stonebridge clients

Is Stonebridge off your patch?

Not at all. Stonebridge is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on a block within reach of Thorpe Bay station?

Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.

Can people stay in the building while you reseal?

Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.

What if the old mastic contains asbestos?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

Common problems we fix in Stonebridge

Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one it comes away from one face.

It’s worth sending us details if you spot any of the following:

  • The same joint failures repeated across a portfolio
  • Draught complaints from residents or tenants
  • Complaints coming in block by block
  • Cracked, hardened mastic round windows on a block

With historic buildings such as Southchurch Hall, 2.1 miles to the south-west of Stonebridge, in the wider area, owners of older properties around Stonebridge should expect mastic to need a product that suits old masonry.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • How they’ll work around occupants
  • Will RAMS and insurance details be available?
  • Their public liability cover
