Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How a job runs

We begin with a short walk round with whoever looks after the building, 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. Rural sites near Shawford may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. The sequence is agreed with the site manager.
  4. Each area is sealed when it’s released.
  5. Joints are prepared, backed and sealed to the specification.
  6. After snagging, the work is handed over under our 12-month guarantee.

Advice

How we handle construction mastic in Shawford

Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal sealing often fills those days. We work on window and door perimeters, sanitary and kitchen joints and internal decorators’ caulk, and the usual reasons a site gets in touch are perimeter gaps outside the sealant’s range and bath and shower joints scraped during the final clean. A specialist sealant contractor works differently from a general builder: on jobs in Shawford, preparation and product choice get the time they need.

Construction in and around smaller places such as Shawford is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Construction mastic around Shawford: what changes locally

Shawford sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Shawford lies roughly 63 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

For contractors refurbishing units at places like Hazeley Enterprise Park, 0.9 miles east of Shawford, the mastic covers cladding panels, roller-door and window perimeters. University estates such as University of Winchester, 2.6 miles to the north of Shawford, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. School extensions, at buildings such as Compton All Saints Church of England Primary School, usually run to the summer holidays, mastic included.

Shawford is about 3 miles south of Winchester, in Hampshire. If you are looking for construction mastic in Shawford, we can help, as we do across Hampshire. Across Hampshire, 723 places are covered, including Shawford. There’s a separate page for Southampton, about 8 miles away.

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Shawford can form part of a wider programme.

What sets the cost

Before we quote, we look at:

  • Working within restricted access windows
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first
  • Any access equipment needed

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you are ready.

Sending details for a quote

Whether it’s one area or a whole building, these details speed things up:

  • Any specification or named product
  • The type of building and who uses it
  • A wide shot and a close-up of the area
  • Drawings or a marked-up plan, if available

To get a fixed quote, call 01277 525 020 or email the details over, telling us the site location and the nature of the job. Our quote form is another easy route.

Common questions from Shawford clients

Do you take on work at healthcare sites like Wessex Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Could you schedule work at a campus like University of Winchester for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email us. Include photographs or drawings if you have them.

What happens if the weather stops external sealing?

Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing.

Is the mastic package guaranteed?

It’s backed by our 12-month guarantee on the workmanship. Protecting sealed areas from following trades helps avoid damage.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

What accreditations do you hold?

Our applicators hold CSCS cards, and we are CHAS accredited and a Constructionline member. We are also fully insured, with five million pounds of public liability cover.

What the job involves on each surface

Window and door perimeters

Internal perimeters are typically sealed with a paintable product where decorating follows. The specification decides which with colours matched to the frame where needed.

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.

Why it’s worth doing now in Shawford

Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility. Older rural buildings around Shawford move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
