- Sealant peeling off a dusty or damp surface
- Decorators’ caulk around a bath or shower
- Black mould underneath the bead
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Never seal over old silicone
- Check ceilings under showers for marks
- Deal with small splits early
- Run the fan after every shower
Keep the room ventilated: run the fan during and after showers, or open a window.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.

Different surfaces, different methods
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is normally part of the cause. Along with resealing, we will mention if the room needs better ventilation.
Landlords, agents and businesses in Astwood
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too in Astwood and across Milton Keynes. We can quote a run of properties together, and we are fully insured.
Remedial sealant in Astwood: local notes
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Rented homes near Kempston Hardwick station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Homes close to Church of St Peter include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Common questions in Astwood
Is Astwood in your area for remedial sealant?
Yes, Astwood is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Will you come out to Astwood?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you take off two layers of silicone?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s what makes the new bead last.
My shower still leaks after a reseal. Can you sort it?
Yes. First we check whether the leak is the sealant at all, then strip and reseal the joints.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before any work starts.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
The process
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours, depending on how many layers have to come out, and we explain the cure time before we leave. For a village or hamlet like Astwood, the journey is planned in advance: 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.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work

We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Movement from fittings that are not supported
- Water damage behind tiles that needs a tiler

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
