Mastic sealing across Hampshire: what to expect

For blocks and buildings across Hampshire, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. The enquiries we see most involve movement joints with sealant missing and draughts at frames across a block, on communal entrances and stairwells, window and door perimeters on blocks and communal kitchens and washrooms.

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work.

Each block or building is walked and the failed joints recorded with the likely cause.
You get a fixed quote, priced per building where that helps your budgeting.
The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
We remove the old mastic completely and clean the joint faces back.
Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
Each building is checked on completion and the work carries our 12-month guarantee.

What you will pay

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Blocks and managed buildings across Hampshire

Across Hampshire, from Basingstoke, Winchester and Gosport outwards, managing agents, landlords and housing associations look after blocks, mixed-use buildings and estates. Window and door perimeters and external joints on them need renewing as the mastic ages.

We work across Greater London and the South East counties, and every job in Hampshire starts with access, parking and site rules. Along the coast in Hampshire, hospitality buildings tend to be busiest in the summer months, so work is often best planned for quieter months.

Basingstoke: Churches, halls and community buildings such as St Michael's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Property owners at sites such as Thornycroft Industrial Estate, less than half a mile south-west of Basingstoke, can have mastic renewed between lettings.

What happens if it’s left?

Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work with less control over timing.

Quoting for work in Hampshire

Your fixed quote is built from the real scope. It allows for:

Location, for remote and island sites
Induction, permit and paperwork requirements
Any access equipment needed
Specialist products, such as fire-rated or hygienic sealants

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

Access details, including height
Approximate linear metres or a joint schedule
Your programme or deadline
The site address and postcode

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

Failed window or door frames, which need a window contractor
Glazing that needs replacing
Masonry that has broken away beside the joint

Looking after the joints

Regular inspection catches problems early. In particular:

Make mastic part of routine maintenance checks
Make it easy for occupiers to report draughts
Keep a record of when each building was resealed
Plan resealing building by building rather than complaint by complaint

Keep records of when each building was resealed. That makes future programmes easier to plan and gives you a history.

The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.

Commercial clients in Hampshire

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Common questions from Hampshire clients

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Is asbestos a concern with old mastic?

Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

Do you work with property factors and landlords?

Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What paperwork can you provide?

Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.

What will the job cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
