Leave it or put it right?
Sealing over the old bead can seem the fastest option, but it won’t bond, and it lifts again soon. One proper reseal beats several quick ones. In a small place like Burnham Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

How it works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take a morning for a small washroom, and a planned programme for bigger sites. Somewhere like Burnham Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We agree a programme with you: which rooms, in what order, at what times.
- Tell us what paperwork your site needs, and we confirm what we can supply before we start.
- Old sealant is cut out room by room and joints cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
How to prepare
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

Aftercare tips
Good habits help new joints last longer. Our tips:
- Give housekeeping the cure time for every room
- Leave squeegees in busy showers
- Keep strong chemicals and scourers off the joints
- Check the joints during routine room inspections
We give a cure time for every area we finish, usually around 24 hours. Pass it on to housekeeping or cleaners so the new sealant is not wetted or scrubbed too soon.
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.
What affects the quote in Burnham Green
You will get a clear quote before any work starts. It’s based on:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Any working-time requirements on site
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Where the property is
- The type of property
- If someone has resealed it before
- What’s wrong with the joints now
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, ring 0345 464 0079 or drop us an email.

A rushed reseal between guests rarely lasts. Sealing over old silicone, sealing wet joints or using the wrong product means the joint fails again soon.
Look out for any of the following:
- Split sealant where wet room floors meet walls
- Shower leaks reaching the floor below
- Failed joints in office kitchens and tea points
- Washrooms that need sorting before an inspection
If you look after a building such as Monk's Walk School, busy washrooms and kitchens can be resealed in phases so they stay open.
