Construction mastic in Viables
Mastic is often where a new building first shows its quality to the client. Untidy or missed joints are among the commonest snag items and clearing them late eats into the handover window. We seal so the snag list stays short. Most enquiries involve existing joints on a refurb that need cutting out and resealing and snag items on joints that need redoing before handover, across brick and block movement joints, floor and skirting junctions and internal decorators’ caulk. Whoever orders the work in Viables, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around places like Viables, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Viables can sit alongside others in a wider programme across Hampshire.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
How the job changes by surface
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps so we’ll flag where the detail needs something different. Tell us what records you need and we’ll confirm with the quote.
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified, and colour-matched products can be used where the frame is on show.
Facades, frames and programmes in Viables
Central London is about 46 miles from Viables. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
Hotels like Audleys Wood Hotel, less than half a mile south-east of Viables, rarely close for long, so refurbishment mastic is phased floor by floor. Hospital estates such as Basingstoke and North Hampshire Hospital (to the north-west of Viables) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. For contractors at a school such as St John's Church of England Voluntary Aided Primary School, sealing has to be finished before term starts.
Viables is about 1 mile south-east of Basingstoke, in Hampshire. Across the RG21 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Hampshire, 723 places are covered, Viables among them. For work in that direction, see our Reading page.
Anyone looking for construction mastic in RG21, RG22 and RG25 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Just outside Viables, we also work in Cliddesden (1 mile south), Eastrop (1 mile north), Oakridge (1 mile north), Lychpit (2 miles north-east) and Old Basing (2 miles north-east).

Quoting for work in Viables
We price every job individually. The main factors are:
- The size and state of each joint
- Phasing around occupants
- Any access equipment needed
- How much existing material needs removing
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
What to include in your enquiry
Whether it’s one area or a whole building, these details speed things up:
- Your programme or deadline
- Access details, including height
- A wide shot and a close-up of the area
- What the building is and how it’s used
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Your questions answered
Is a hospital such as Basingstoke and North Hampshire Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Could you schedule work at a campus like Queen Mary's College for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can the sealant be colour-matched?
It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you fit around our programme?
The programme sets the job. Tell us the sequence and we’ll plan applicators around it.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Deciding which fire-stopping product a penetration needs
- Designing joint widths or choosing the specification (that sits with the designer)
- Damage to finishes by other trades after we have sealed
If you’re not sure, just ring 01277 525 020 or email the details over and we will give you a straight answer.
Where we work in Viables
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Brick and block movement joints
- Floor and skirting junctions
- Cladding and panel joints
- Window and door perimeters
Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Ask installers to correct oversized gaps first
- Keep finished joints away from paint, plaster and scrapers
- Keep scrapers and abrasive pads off new beads
- Allow flexibility for external sealing in damp or cold weather
Record which products went where in the handover file. That helps the building owner maintain the joints later. Tell us what records you need and we’ll confirm with the quote.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We flag them as soon as we see them.
How a job runs
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Several jobs near Viables can be grouped on one trip. Tell us your site hours and we’ll plan around them.
