Mastic sealing for commercial buildings in Bitterne
Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. Most enquiries involve leaks at window and door perimeters and open joints in brickwork or panels, on communal entrances and stairwells, external wall and movement joints and communal kitchens and washrooms. Most enquiries from Bitterne start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Places the size of Bitterne normally have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Planned mastic for Bitterne portfolios
Bitterne lies within about 2 miles of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. Bitterne lies roughly 68 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Landlords with units on estates such as Bitterne Business Centre (0.8 miles west of Bitterne) can bring frame, door and external mastic across several units into one programme. Schools and community buildings such as Bitterne CE Primary School need frame and external mastic kept sound like any building. Buildings close to stations like Bitterne station (0.7 miles north-west of Bitterne) are often flats over shops, with frame mastic to keep sound.
Bitterne is about 1 mile east of Southampton, in Southampton. We cover commercial sites throughout Bitterne, whether it’s a single job or part of a planned programme. Across Southampton, 30 places are covered, including Bitterne.
We cover the SO18 and SO19 postcode districts for mastic joints. If your site is on Bath Road, Ruby Road and Dean Road or close by, we can quote for mastic joints.

We also cover Northam (1 mile west), Bitterne Park (1 mile north-west), Itchen (1 mile south-west), Midanbury (1 mile north) and Harefield (1 mile north-east) for mastic joints. Bigger towns within reach include Shirley (3 miles west), Regents Park (3 miles west), Maybush (4 miles west), Coxford (4 miles west), Freemantle (3 miles west) and Lordswood (4 miles north-west).

On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a site in Bitterne, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Before we start on site
- Tell staff and tenants when we’ll be in
- Point out any areas we must not close
- Let us know about inductions and permits

Advice
Different surfaces, different methods
Tenement and older buildings
Natural stone can be marked by the wrong sealant, so we pick a grade that won’t mark it.
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
What happens if it’s left?
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. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Bitterne: questions and answers
Do you work in occupied care homes around Bitterne?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
Is Bitterne off your patch?
No. Places such as Bitterne are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Do you work for managing agents and housing associations?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure.
How many days will you need on site?
That varies with the scale of the job, though a typical visit usually takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Masonry that has broken away beside the joint
- Materials that need asbestos testing before work
- Leaks through the frame itself rather than the perimeter
If you’re not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
Joints and surfaces we work on
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- External wall and movement joints
Doing it in-house
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
