About our construction mastic in Grateley
Mastic follows everyone else, which means it absorbs every delay upstream. We agree a sequence at the start and adjust it as the site manager releases areas, so applicators arrive when areas are genuinely ready. Sealing too early only means coming back once others have damaged it. If you’re dealing with existing joints on a refurb that need cutting out and resealing and missed perimeter joints on a new elevation, we can put it right, on sanitary and kitchen joints, internal decorators’ caulk and floor and skirting junctions alike. Whoever orders the work in Grateley, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Construction in and around smaller places such as Grateley 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.
A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or email the details over and we will come back to it.

Grateley: questions and answers
Is Grateley off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can the mastic package for our job in Grateley follow the site programme?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can you fit around our programme?
We seal plot by plot or floor by floor as areas are released. The sequence is settled with your site team.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Leave it or put it right?
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to. Damaged joints are removed and resealed from clean faces. Older rural buildings around Grateley move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why appoint us
- CHAS accredited

Construction mastic around Grateley: points for this area
Grateley lies roughly 69 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. Grateley sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.
Hospital estates such as Andover War Memorial Hospital, 5.4 miles to the north-east of Grateley, 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.
Grateley is about 6 miles south-west of Andover, in Hampshire. Grateley sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Grateley is one of 723 places we cover in Hampshire for mastic packages. Southampton is covered too, around 20 miles from Grateley.
If you need construction mastic in SP11, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Signs you need construction mastic in Grateley
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding.
Any of the following is a good reason to get the joints checked over:
- Mastic snags holding up handover
- Different trades sealing to different standards
- Caulk cracking where joints are moving more than expected
- Perimeter gaps outside the sealant’s range
For contractors at a school such as Grateley Primary School, sealing has to be finished before term starts.
What to look for in a quote

Other services in Grateley
From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Jobs in and around smaller places like Grateley are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Getting the site ready
- Warn occupants and staff about the work
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What affects the price in Grateley
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Access and working height
- Backing rod, priming and other preparation
- Travel to remote or island sites
- Phasing around occupants
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- When you need the work done
- Any specification or named product
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, speak to us on 01277 525 020 or email the details over.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
