Advice
How we handle construction mastic in Well
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, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. If you’re dealing with missed perimeter joints on a new elevation and oversized or tapered gaps around new frames, we can help. For commercial sealant work in Well, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places like Well, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we will arrange a return visit.

General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
How the job changes by surface
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.
Contractors’ notes for Well
Well is about 40 miles 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. Well sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.
Historic houses such as Farnham Castle (4.8 miles east of Well) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. On a campus such as University for the Creative Arts, 4.6 miles to the east of Well, new teaching buildings and residences are usually built and refurbished around the academic year. Projects at schools like Lord Wandsworth College work to term dates, so mastic is programmed tightly.
Well is about 5 miles west of Farnham, in Hampshire. Looking for construction mastic in Well? We can help. Our Hampshire coverage takes in 723 places. Sites around Reading have their own page, roughly 16 miles from Well.

Cost factors for mastic packages
Each job is priced on its own details. The things that drive the figure:
- The size and state of each joint
- How much there is to seal
- Induction, permit and paperwork requirements
- Which sealant the job calls for
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What we need to price the job
A few photos plus some basic facts will normally do. Please tell us:
- The product your specification calls for
- A wide shot and a close-up of the area
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available

Questions we’re asked in Well
Can you take on a job at a hospital such as Spire Clare Park Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Well too small for you to travel to?
No. Places such as Well are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
What will the job cost?
Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or email us with a description of the work.
Can you come in just for snagging?
Yes. Share the list and photos, and a fixed quote follows, then clear it to your programme.
For managing agents and facilities managers
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Why it’s worth doing now in Well
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. We cut out and redo the joint properly. One visit to deal with every failing joint makes more sense than several trips to a place like Well. Send photos of each area and we will quote for the lot.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
