FAQs: Southampton
Can you work at a site such as Bitterne Business Centre, by Southampton?
Yes, sites like Bitterne Business Centre are within our area, along with the rest of Southampton. A few photos and the unit address let us price the work.
Does a coastal location like Southampton affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
About our facade sealing in Southampton
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on stone and brick facade joints, cladding panel joints and coping and flashing joints, and what we are called in for most is gaps between rainscreen or cladding panels and leaks at window and door perimeters. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Southampton is the same: the right product in a properly prepared joint.
Places the size of Southampton tend to see a steady run of new-build and refurbishment schemes. For main contractors and developers, the mastic package covers window and door perimeters, facade and cladding joints, and internal sealant where it’s specified.
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’re clear about what is covered before work starts.

Owners, agents and contractors
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Southampton can sit alongside others in a wider programme across Southampton.
When to call us in Southampton
Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.
Clients normally get in touch after noticing one or more of the following:
- Air leaks through failed facade joints
- Failed sealant on precast panel joints
- Weathered facade joints that have lost their grip
- Sealant pulling away from frames or panels
Units on estates such as Bitterne Business Centre (0.7 miles east of Southampton) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

General trades versus a specialist
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 where general trades tend to cut corners.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

What else we do in Southampton
Why act early in Southampton
Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. On a busy site in a large place like Southampton, a failed joint gets worse with every day of use. Acting early keeps it a sealant job.
A quote for facade joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

Contractors’ notes for Southampton
With the shore within about 2 miles, Southampton counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
University estates such as University of Southampton, 0.7 miles to the north-west of Southampton, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Extensions at sites like Royal South Hants Hospital (to the south of Southampton) typically sit beside working departments, and the mastic follows strict access rules.

Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Jobs in a large place like Southampton are often on business parks, retail sites or campuses with their own sign-in and permit rules. Send the site rules with your enquiry and we will plan to them.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Tell us what induction or permit system the site runs
- Make sure the joints can be reached

Advice
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Share access with other external trades
- Note when each elevation was last resealed
- Walk the elevations once or twice a year
- Insist on a full cut-out when joints are renewed
Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.
