Mastic sealing for commercial buildings in Stone
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. Site teams most often ask us about repeated reactive repairs to the same buildings and window mastic that has split and shrunk, on external wall and movement joints, balcony and threshold joints and window and door perimeters on blocks.

Rural conversions near places like Stone often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Why deal with it now?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Older rural buildings around Stone move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Common questions from Stone clients
Do you take on block-wide or estate-wide mastic work in Stone?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
Our building in Stone is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Do you work for managing agents and housing associations?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Do you cover Stone?
Yes. We cover Stone, within our coverage of Greater London, South East England and Scotland. To discuss a job, phone 01277 525 020 or email drawings and photos.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What about access for upper-floor joints?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. If others near Stone need work, visits can be combined. You will have a fixed quote before work starts.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Make sure the joints can be reached
- Tell us your opening times and when work is allowed
- Point out any areas we must not close

Advice
Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

What else we do in Stone
Block-wide mastic in Stone
The sea is no more than about 1 mile from Stone. On buildings near the shore, the side facing the weather usually needs its mastic renewed first, and they deserve more regular inspection. Rainfall across the South East, Stone included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
Trustees of buildings like St Francis can bring frame and external mastic into a planned maintenance list. With historic buildings such as Beaulieu Palace House (to the north-west of Stone) in the wider area, owners of older properties around Stone should expect mastic to need a product that suits old masonry.

Work for main contractors and building owners
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Honest limits
Honesty saves time and money. Fresh joints won’t solve:
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Failed window or door frames, which need a window contractor
- Leaks from above rather than through a joint
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think.
