How we handle commercial sealant in Lyneham
Mouldy or split sealant in a commercial building causes more than a bad impression. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. If you have worktop sealant that has shrunk and stained and whole floors of tired en suites, we can help, whatever the surface.
For a small place like Lyneham, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
You’re covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Workplaces and buildings in Lyneham
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Why deal with it now?
Sealing over the old bead can seem the fastest option, but it will not bond, and it lifts again soon. Doing it properly once is less disruptive than doing it badly twice. Where a wall is exposed, as many are in small places like Lyneham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Get split or lifting joints looked at early
- Check the joints during routine room inspections
- Pass on the cure time to whoever cleans the rooms
- Keep a record of which rooms were resealed and when
Each room is handed back with its cure time, generally around 24 hours. Make sure housekeeping or cleaning staff know it so nobody showers or cleans the joint too early.
It’s easier to plan a programme than to react to failures. Rooms can be scheduled around occupancy and staff, rather than closed at short notice.
The process
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours per area, with larger sites planned over several visits for a typical job. Somewhere like Lyneham needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
