Mastic sealing for commercial buildings in Bassett Green
Owners and agents normally inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. If you are dealing with patchy repairs in mismatched sealant and failed external movement joints, we can help, whatever the surface. A single leaking joint is often how a building in Bassett Green first comes to us: we look at the rest while we’re there and tell you what we find.
For landlords and associations with stock in and around Bassett Green, grouping buildings into one visit saves travel. One quote can cover a whole list of addresses.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Work for main contractors and building owners
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Bassett Green can form part of a wider programme across Southampton.
How the job changes by surface
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading so the work is phased.
Communal areas
We keep entrances and stairs open throughout. We work in sections so access is never blocked.
How the quote is worked out
To price the job, we consider:
- Access and working height
- Phasing around occupants
- Removal of failed or old sealant
- The total length or number of joints
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.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- Any specification or named product
- Whether the building will be occupied during the work
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or use the quote form.
Questions we are asked in Bassett Green
Our building in Bassett Green is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you work at a site such as Belgrave Industrial Estate, by Bassett Green?
Yes. We cover Bassett Green and the area around it, including industrial estates, business parks and retail parks such as Belgrave Industrial Estate. To start, just call the office on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
What paperwork can you provide?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Can you take on resealing for a block portfolio?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Why it’s worth doing now in Bassett Green
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If neighbouring businesses or buildings around Bassett Green need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
What we need from you
- Make sure the joints can be reached
- Tell us which areas need to stay in use
- Let us know about inductions and permits
