DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we are called out for in Burnham-on-Crouch
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, cannot flex, and tears at the first real movement. Backing sets the depth and stops that.
People usually contact us after spotting one of these:
- Black mould underneath the bead
- Beads that never stuck properly
- Gaps opening along the back of the worktop
- Leaks that keep coming back after resealing
In the older streets around St Mary's Church, walls and floors in older homes can move, and sealant and grout show it first.

Quotes for remedial sealant in Burnham-on-Crouch
Some jobs are bigger than they look, and some smaller. The main factors:
- How many areas need sealing
- The product the joint needs
- Any working-time requirements on site
- The amount of work
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- Any previous sealing or DIY work
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.
Surface by surface
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We’ll tell you what we find.
Why deal with it now?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. Homes in smaller places like Burnham-on-Crouch can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clean sealant with mild products only
- Never seal over old silicone
- Keep movement joints clear of mortar and paint
- Get the cause of a repeat leak found before resealing
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours, depending on how many layers have to come out for a typical job. In a smaller place like Burnham-on-Crouch, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we are working on
