Looking after the joints
Keep the joints in good shape with a few simple steps:
- Log resealing dates block by block
- Prioritise elevations facing the weather
- Check sealant joints during planned building inspections
- Ask residents or tenants to report leaks and draughts early
Keep records of when each building was resealed. That makes future programmes easier to plan and gives you a history.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
Mastic sealing in Clanville
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable. We will confirm the colours available for the specified product. The enquiries we see most involve repeated reactive repairs to the same buildings and communal area joints that look neglected, on communal kitchens and washrooms, balcony and threshold joints and external wall and movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Clanville is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Clanville, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What the job involves on each surface
Planned maintenance
Planned resealing replaces emergency callouts and spreads the work.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Clanville need work, visits can be combined. You’ll have a fixed quote before work starts.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- Confirm the product named in the specification
- Tell us which areas need to stay in use
- Make sure the joints can be reached

FAQs: Clanville
Do you cover business parks and estates near Clanville, such as Weyhill Business Park?
Yes, sites like Weyhill Business Park are within our area, along with the rest of Clanville. A few photographs and the unit address let us price the work.
Is a smaller place like Clanville outside your area?
Not at all. Clanville is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can you quote from photographs?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
Why it’s worth doing now in Clanville
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. Around Clanville, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why us?
- Products installed to the manufacturer’s instructions
- Coloured sealants to suit the setting, where available
- 12 months’ guarantee on every job
- Colours chosen to suit frames, cladding or finishes where possible

Frames, entrances and external joints in Clanville
Clanville is about 65 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Clanville sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you own or manage units on a site such as Weyhill Business Park, which lies south-west of Clanville, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Churches, halls and community buildings such as St Margaret's Chapel are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If your remit includes a building such as Appleshaw St Peter's CofE Primary School, frame and door mastic can be programmed for the holidays.

Honest limits

- Materials that need asbestos testing before work
- Broken glass or failed sealed units
