Keeping the joints sound
After handover, a little attention goes a long way:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Keep a record of which joints were resealed and when
- Act on the first lifting edges rather than waiting
- Make sure contractors see the asbestos survey before cutting out old mastic
Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. If anything looks wrong, give us a call on 01277 525 020 or email drawings and photos with a photo.
Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.

Common questions from White Waltham clients
Is White Waltham too small for you to travel to?
No. Small places get the same service as large ones. 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 the sealant on our White Waltham premises match the finishes?
Yes, we can typically get close to most finishes from the product’s colour range. Send colour references or photographs and we will confirm what’s available for the product.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
What guarantee do you give on resealing?
Our workmanship on each job is backed by a 12-month guarantee. We’re fully insured for public liability as well.
How long does a job like this take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
How do we get a quote?
Photos, drawings or a schedule of the joints are normally enough to start through the quote form on this site. If a visit is needed we’ll book one, and a fixed quote follows.
Do you need commercial sealant contractors in White Waltham?
A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. Getting back to a clean joint then means removing every layer.
Typical triggers for a call:
- Black mould through washroom sealant that won’t clean off
- Movement joints packed with grit and debris
- Earlier reseals applied straight onto the failed bead
- External beads that have gone brittle and cracked
For tenants and agents on sites such as Grove Business Park, less than half a mile to the north-west of White Waltham, office fit-outs, reception joints and window perimeters are the usual sealant work.
What to look for in a quote
- Will CSCS-carded applicators be on site?
- Health and safety accreditation such as CHAS
- The terms of the workmanship guarantee
- What level of public liability insurance do they hold?
Why deal with it now?
A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. In many cases the element is fine and only the seal around it has given up. Resealing normally costs far less than renewal, though we will tell you honestly if the element itself is the problem. Converted and older buildings near places like White Waltham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Surface by surface
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. Tell us your trading hours and access windows and we will plan around them.
Commercial kitchens and tea points
Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing, with a food-safe or hygienic product wherever food contact can happen.

Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
