What the job involves on each surface
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we’ll plan around them.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Mastic sealing in Redenham
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. We work on window and door perimeters on blocks, communal kitchens and washrooms and external wall and movement joints, and what we are called in for most is movement joints with sealant missing and the same joint failures repeated across a portfolio. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Redenham, that means joint design, primers and backing rod as standard.
In and around smaller places like Redenham, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What else we do in Redenham
Work for main contractors and building owners
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Redenham. Several sites can go on one quote, which keeps the paperwork simple.
When to call us in Redenham
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.
Things that normally lead to an enquiry:
- Estate-wide sealant that is simply worn out
- Old repairs sealed over failed mastic
- Failed external movement joints
- Damaged joints in communal entrances and corridors
Older community buildings, Church of St Peter in the Wood among them, often have frames of mixed ages whose mastic varies.
Questions to ask before you book
- Their approach to joint depth and backing
- Can the work be phased to keep areas open?
- The named product and why it was chosen
- How long is the guarantee, and what does it include?
How a job runs
The first thing on site is a walk round with your contact, 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. Smaller jobs around Redenham can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- 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
- Agree which areas must stay open
- Tell staff and tenants when we will be in
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Advice
Maintenance after handover
For the best life from the joints:
- Protect low-level joints in entrances
- Mention RAMS, insurance or CSCS requirements up front
- Log resealing dates block by block
- Prioritise elevations facing the weather
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
Frames, entrances and external joints in Redenham
Redenham is about 66 miles from central London. Managed blocks of flats are a big part of commuter-belt property. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
Blocks of flats and mixed-use buildings often cluster around stations such as Andover station (to the south-east of Redenham) and their window and balcony mastic tends to age at the same rate across a building. For a school such as Appleshaw St Peter's CofE Primary School, perimeter mastic on windows and doors is a holiday job.
Redenham is about 4 miles north-west of Andover, in Hampshire. Across the SP11 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 723 places across Hampshire fall within our area, Redenham among them. For work in that direction, see our Southampton page (24 miles or so).

Why deal with it now?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. One visit to deal with every failing joint makes more sense than several trips to a place like Redenham, rather than one at a time. Send photographs of each area and we will quote for the lot.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
