Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What happens if it’s left?
It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification. Leave it late and they turn up on the snag list. For businesses and landlords in Andover, a tidy, sound joint also matters for appearance. Renewing it keeps the building looking cared for.
A quote for mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

About our construction mastic in Andover
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. If you’re dealing with sealant knocked or painted over by other trades and different trades sealing to different standards, we can put it right. For commercial sealant work in Andover, you deal with one contact from quote to sign-off, whether it’s one building or several.
For contractors on site in a town like Andover, the mastic has to fit the programme: perimeters sealed before scaffold is struck, internal sealant after decoration, snags before handover. Send drawings and the programme and we will price to suit.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Commercial clients in Andover
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Andover can form part of a wider programme across Hampshire.
Cost factors for mastic packages
Your fixed quote is built from the real scope. It takes account of:
- Whether the work must be split into stages
- Which sealant the job calls for
- The site’s rules and procedures
- Any access equipment needed
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.
Sending details for a quote
We can often quote from photos and a few details. Please tell us:
- The site address and postcode
- Specification clauses that apply
- How the joints are reached, and at what height
- Any dates the work must fit around
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Andover: questions and answers
Could you schedule work at a campus like Andover College for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Northern Avenue Retail Park, near Andover, within your area?
Yes, sites like Northern Avenue Retail Park are within our area, along with the rest of Andover. Photos and a short description are enough for a first look.
Do you do internal caulk as well as external mastic?
The scope comes from the specification and drawings, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
Can staff carry on working while you are here?
In most cases, yes. We phase the work so most of the building stays in use.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
What guarantee comes with a mastic package?
Each package is backed by a 12-month guarantee. We’re also fully insured for public liability.
Do you install fire-rated sealant as part of a package?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. Fire-stopping design and sign-off sit with the designer and building control.
How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Town-centre premises in Andover may have limited parking, so tell us what’s nearby. On estates and business parks it’s typically simpler.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Point out any areas we must not close
- Tell us what induction or permit system the site runs
- Confirm the product named in the specification

Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Damage to finishes by other trades after we’ve sealed
- Glazing units that are cracked or misted
- Designing joint widths or choosing the specification (that sits with the designer)
If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think before you book.
Joints and surfaces we work on
- Cladding and panel joints

Construction mastic around Andover: how the place shapes the job
The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. There are several hotels within about 2 miles of Andover. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
For contractors at a school such as St John the Baptist Catholic Primary School, sealing has to be finished before term starts. Hotel extensions and refits, at places such as The Globe Hotel, under half a mile south-east of Andover, typically run between busy periods, so the sealing is squeezed into short windows. For a contractor working at a hospital such as Andover Hospital (Grounds), which lies north-west of Andover, perimeter and facade sealing is planned around patients and deliveries.
Andover is about 17 miles west of Basingstoke, in Hampshire. If you are looking for construction mastic in Andover, we can help. Across Hampshire, 723 places are covered, including Andover. Southampton is covered too, some 21 miles away.
Work on mastic packages is covered throughout SP10 and SP11, for business premises of every kind. Buildings on High Street, Goddard Square and London Road are within our area for mastic packages. You will find Andover on or near the A303 and A342, so getting applicators and materials to site is simple. Nearby places we also cover include Picket Twenty (1 mile east), East Anton (1 mile north-east), Knights Enham (1 mile north), Finkley Down (2 miles north-east) and Picket Piece (2 miles east) for mastic packages. A short drive away, we cover Winchester (13 miles south-east), Romsey (15 miles south), Hyde (12 miles south-east), Tidworth (8 miles west), Weeke (12 miles south-east) and Kempshott (15 miles east). Among the larger centres in Hampshire is Andover, and we take on mastic packages for its commercial and public buildings.
Local landmarks in Andover
We work on buildings around The Angel Inn, Winton Community Academy and Winton Community Academy. Andover’s nearest station is Andover station, roughly 0.5 miles west of the centre. Nearby you will also find Andover War Memorial Hospital (0.7 miles north-west) and Andover Museum (less than half a mile east). The countryside around Andover includes Anton Lakes and Mill Lake.
After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Put any product change through the designer first
- Share drawings and the specification as soon as possible
- Keep finished joints away from paint, plaster and scrapers
- Keep product details for future maintenance
The package carries our 12-month guarantee for workmanship. The guarantee covers how we sealed, not later damage by other trades which is why protection after sealing matters.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. A check of every frame before decorators start is worth the time.
