How we handle facade sealing in Inner Avenue
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. We work on shopfront frames, perimeter joints where frames meet the structure and cladding panel joints, and the failures we are asked to look at most are cold air coming in at window perimeters and unsightly perimeter sealant on a visible elevation. A specialist sealant contractor works differently from a general builder: on jobs in Inner Avenue, preparation and product choice get the time they need.
On a small site around Inner Avenue, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Do you need facade sealing in Inner Avenue?
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
These are often picked up first by site or facilities staff:
- Discoloured or dirty facade joints
- Weathered facade joints that have lost their grip
- Patch repairs that keep failing
- Weathered joints at frame-to-structure perimeters
For contractors refurbishing units at places like Mountbatten Retail Park (0.9 miles south-west of Inner Avenue), the mastic covers cladding panels, roller-door and window perimeters.

Contractors’ notes for Inner Avenue
Inner Avenue lies within about 2 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. 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.
Building work at universities like Solent University, 0.6 miles south of Inner Avenue, is often timed for the summer, mastic included. Work at a hotel such as Elizabeth House Hotel (to the north-west of Inner Avenue) tends to be programmed around bookings, mastic included.
Inner Avenue is about 1 mile west of Southampton, in Southampton. We cover Inner Avenue, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 30 places in Southampton, large and small.

On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Work in places the size of Inner Avenue is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- 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.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs
- Share your working hours and any access restrictions

When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Damaged frames that need replacing
- Work on the window or framing system itself
- Water getting in through cracked render or porous masonry
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.
What we seal
- Cladding panel joints
- Window and door perimeters
- Shopfront frames
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Stone and brick facade joints
Building owners, agents and FMs in Inner Avenue
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Inner Avenue can sit alongside others in a wider programme.
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.
Why deal with it now?
Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
Why appoint us
- Colour agreed before work starts
- Fully insured, including public liability cover
- One contact handling all your sites
- Over 20 years of commercial sealing

Common questions from Inner Avenue clients
Would you work within a site like Royal South Hants Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you plan work around the academic year at somewhere like Solent University?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
