Stonehill construction mastic
Work needed on a mastic package in Stonehill? We look at it, seal it with the right product and hand it over with a 12-month guarantee.
- Existing joints on a refurb that need cutting out and resealing
- Bath and shower joints scraped during the final clean
- Frame gaps too wide for sealant alone
Construction mastic for Stonehill sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What the job involves on each surface
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control and we install what’s specified.
Construction mastic for commercial buildings in Stonehill
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. That keeps the work right first time and saves rework. Most enquiries involve external joints sealed in damp or cold conditions that are now failing and sanitary sealant damaged by following trades, on sanitary and kitchen joints, brick and block movement joints and cladding and panel joints. One point of contact handles commercial sealant work in Stonehill from the first photos to the final walk-round, whether it’s one building or several.
Construction in and around smaller places such as Stonehill is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Rural sites near Stonehill may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
What we need from you
- Tell staff and tenants when we will be in
- Move anything stored against the joints
- Tell us your opening times and when work is allowed

Common problems we fix in Stonehill
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with. Better to raise it at the start than seal a joint that’s bound to fail.
If one of these sounds familiar, it’s time for a closer look:
- Existing joints on a refurb that need cutting out and resealing
- Caulk cracking where joints are moving more than expected
- A long mastic snag list close to completion
- Inconsistent sealant finishes from plot to plot
Extensions at sites like St Peter's Hospital, 1.7 miles north-east of Stonehill, usually sit beside working departments, and the mastic follows strict access rules.
What your quote should include
- Who will actually carry out the work
- What site paperwork they can supply
- How long is the guarantee, and what does it include?
- Are they CHAS accredited or on Constructionline?
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Joints damaged after sign-off by following trades
- Designing joint widths or choosing the specification (that sits with the designer)
- Approving fire stopping as compliant
If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we’ll say what we think.
Joints and surfaces we work on
- Cladding and panel joints
- Brick and block movement joints
- Window and door perimeters
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Floor and skirting junctions
Questions we are asked in Stonehill
Can you work around term dates at a campus such as Royal Holloway University?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you take on a job at a hospital such as St Peter's Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Do your applicators hold CSCS cards?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. Public liability insurance of five million pounds is in place too.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
How do you work with the site programme?
Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready.
Contractors’ notes for Stonehill
Stonehill is about 22 miles from central London. 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. Rainfall across the South East, Stonehill included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
When a school such as Salesian School is extended or refurbished, the mastic package is often squeezed into the holidays. Older buildings in the area around Stonehill, such as Botleys Mansion (1.4 miles north-east of Stonehill), need care when sealed: the product has to suit soft or historic materials.
Stonehill is about 3 miles north of Woking, in Surrey. Businesses, contractors and managing agents in Stonehill can call on us for mastic packages. Our Surrey coverage takes in 379 places, from busy centres to rural villages. Sites around Reading have their own page, about 19 miles away.

Near you in Stonehill
Around Stonehill, our work takes us to commercial buildings near Gracious Pond and the streets around them. For rail, the closest station is Longcross station, roughly 2.1 miles north-west. A little further out are Chobham Museum (2.2 miles south-west) and The Peacocks (3.1 miles south). For a walk, there’s Gracious Pond and St Ann's Lake.
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Redoing a failed joint typically 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.
Cost factors for mastic packages
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Joint width, depth and condition
- The site’s rules and procedures
- Quantities, in metres or numbers
- Working within restricted access windows
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- How the joints are reached, and at what height
- Any dates the work must fit around
- Where the site is, with the postcode
- Whether an asbestos survey exists
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
