Mastic sealing for commercial buildings in Farnborough
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. We work on communal entrances and stairwells, window and door perimeters on blocks and balcony and threshold joints, and what we are called in for most is repeated reactive repairs to the same buildings and mastic failing across several blocks on an estate. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Farnborough is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In Farnborough, as in most towns, a block may have frames from several eras, so mastic around them can be of mixed age and quality. A look at the whole building shows which joints need doing now.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Why act early in Farnborough
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once and is simpler to manage and budget. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why appoint us
- One phone line for London, the South East and Scotland
- Matching to RAL references, product permitting
- Our applicators hold CSCS cards
- A Constructionline member, so easy to vet
Different surfaces, different methods
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading, so we plan around them.
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Glazing that needs replacing
- Asbestos-containing sealant, which we don’t remove
Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly.
Surfaces we seal
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
How the quote is worked out
Before we quote, we look at:
- The product specified
- Joint width, depth and condition
- Site requirements such as inductions and permits
- Working within restricted access windows
A quote for mastic joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- Where the site is, with the postcode
- Specification clauses that apply
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email a schedule or drawings.
Maintenance after handover
To get the most from the new sealant:
- Share the asbestos register when you send details
- Include mastic in your cyclical inspections
- Keep bins and bikes away from communal door frames
- Start inspections with the most exposed faces
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
