Owners, agents and contractors
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Whitchurch can form part of a wider programme across Buckinghamshire.
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
About our construction mastic in Whitchurch
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. The enquiries we see most involve window and door perimeters that won’t pass inspection and frame gaps too wide for sealant alone, on sanitary and kitchen joints, floor and skirting junctions and internal decorators’ caulk. Most enquiries from Whitchurch start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a site near Whitchurch, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photos and the programme and we’ll quote to suit.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Looking after the joints
Regular inspection catches problems early. In particular:
- Put any product change through the designer first
- Keep scrapers and abrasive pads off new beads
- Get the mastic subcontractor involved early in the programme
- Brief following trades on areas that have been sealed
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby; we confirm the time for each product.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Joints damaged after sign-off by following trades
- Glazing units that are cracked or misted
- Deciding which fire-stopping product a penetration needs
If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think.
What we seal
- Sanitary and kitchen joints
- Floor and skirting junctions

- Brick and block movement joints
How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and we clear our waste as we work. If others near Whitchurch need work, visits can be combined. A fixed quote is given before anything starts.

Questions we’re asked in Whitchurch
Can work at a site such as University Campus Aylesbury Vale fit around teaching?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is Whitchurch too small for you to travel to?
No. Places such as Whitchurch are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
How many days will you need on site?
It depends on the scope, though a typical visit typically takes whatever the programme allows, since the work follows the trades as areas are released. Larger or phased jobs take longer, and we will give you a timescale with the quote.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
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.
Why deal with it now?
Patching snags as they appear can feel quicker than a proper close-out. But one planned snagging pass through each area typically clears more for less disruption, and avoids repeated visits. We can run snagging as its own phase before handover. Around Whitchurch, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Do you need construction mastic in Whitchurch?
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
What tends to prompt an enquiry:
- Bath and shower joints scraped during the final clean
- Frame gaps too wide for sealant alone
- Different trades sealing to different standards
- Snag items on joints that need redoing before handover
On a healthcare site such as Tindal Centre, 4.2 miles to the south of Whitchurch, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Questions to ask before you book
- What site paperwork they can supply
- The named product and why it was chosen
- Their approach to joint depth and backing
- Their public liability cover
