Construction mastic in Broad Oak, done properly
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. Sealing too early only means coming back once others have damaged it. Most enquiries involve bath and shower joints scraped during the final clean and a mastic package split between trades with no clear owner, across floor and skirting junctions, cladding and panel joints and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Broad Oak, preparation and product choice get the time they need.
Around smaller places like Broad Oak, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our workmanship is guaranteed for 12 months, in Broad Oak as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Questions about Broad Oak
Will you take on work at estates like Murrell Green Business Park, close to Broad Oak?
Yes. Estates, retail parks and business parks around Broad Oak, Murrell Green Business Park among them, are all within reach. A few photographs and the unit address let us price the work.
Do you take on work at healthcare sites like Fleet Community Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you take on mastic snagging only?
Yes. Snag-only work is something we take on and damaged joints are redone properly.
Can you seal external joints in wet or cold weather?
Conditions have to suit the product before external work starts. Wet or cold joints cause adhesion problems.
Do you do fire-rated sealing on new builds?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. The design and sign-off belong to the designer, fire engineer or building control.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Protect sealed areas from following trades
- Keep product details for future maintenance
- Release areas for mastic once other trades have finished in them
- Get the mastic subcontractor involved early in the programme
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead so keep them off the joints.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
How a job runs
Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Broad Oak may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised straight away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site
- Confirm the product named in the specification
- Point out parking and an unloading spot
- Share the asbestos register for older buildings

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Advice
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Designing joint widths or choosing the specification (that sits with the designer)
- Approving fire stopping as compliant
- Joints damaged after sign-off by following trades
If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.

Cost factors for mastic packages
We price every job individually. The main factors are:
- Joint width, depth and condition
- Any access equipment needed
- How much existing material needs removing
- The site’s rules and procedures
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- Asbestos survey details if the building is older
- When you need the work done
- Rough lengths or quantities, or drawings if you have them
- Clear photographs of the problem areas
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or email the details over.
Building and refurbishing in Broad Oak
Broad Oak lies roughly 39 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Broad Oak is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
Projects at schools like Mayhill Junior School work to term dates, so mastic is programmed tightly. Hotels like The George Hotel (to the south-west of Broad Oak) rarely close for long, so refurbishment mastic is phased floor by floor. Units on estates such as Murrell Green Business Park (to the north of Broad Oak) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Broad Oak is about 4 miles west of Fleet, in Hampshire. Commercial clients in Broad Oak use us for work on mastic packages, as part of our coverage of Hampshire. Our Hampshire coverage takes in 723 places. Our Reading page has more on work in that area, about 13 miles away.

What’s near Broad Oak
In Broad Oak, that means premises near The Waterwitch pub and Robert May's School and the streets around them. For rail, the closest station is Winchfield station, about 1.8 miles north. Well-known places in the area include West Green House Agricultural Museum (2.9 miles north) and Hart Shopping Centre (3.8 miles east). For a walk, there’s Fleet Pond Nature Reserve and Tundry Hill.
Why deal with it now?
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites rather than at the snagging stage. Leave it late and they turn up on the snag list. Older rural buildings around Broad Oak move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
