DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

How it works
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the number of rooms. For a village or hamlet like Long Marston, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We walk the site with you and agree the rooms, the order and the hours.
- Each area is protected and the old sealant cut out completely.
- The joints are degreased, treated and left to dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- We check every room and give its cure time for housekeeping.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property

Advice
Aftercare tips
Aftercare is simple:
- Add sealant to your planned maintenance checks
- Log resealing so you know what’s due
- Use mild cleaners on sealant, not bleach or abrasives
- Check extract fans are actually running
Strong chemicals and scourers wear silicone out faster. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.
Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. When you see them, it’s time to plan a reseal.

What the job involves on each surface

Rental portfolios
Between tenancies is a good time to reseal, ready for the next tenant.
Workplaces and buildings in Long Marston
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Managing a site like Long Marston VA Church of England Primary School? Then washroom and kitchen sealant can be programmed around term times or opening hours. Letting a property close to Cheddington station? Then sealant work can be quoted for a single flat or a whole portfolio. Community buildings like Church of All Saints (Church of England) are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.

Leave it or put it right?
Sealing over the old bead can seem the fastest option, but silicone doesn’t bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. Where a wall is exposed, as many are in small places like Long Marston, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
