Remedial sealant & repairs in Sulham, Oxfordshire
Our applicators work in Sulham on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly.
- A second bead peeling off the first
- Wide, uneven beads that look worse than the old ones
- Movement joints that have split or pulled away
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Remedial sealant in Sulham
In Sulham, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. If you have repeat leaks from the same joint and decorators’ caulk around a bath or shower, we can put it right, on botched or over-sealed joints, shrunken worktop sealant and expansion joints alike.
Homes around Sulham are mostly houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What affects the cost of remedial sealant
Your quote is based on your job. We take into account:
- The number of rooms or windows
- The size of the job
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Where the job is, and your postcode
- The problem you’ve noticed
- Pictures of the joints, sent by email
- The type of property
There’s no standard price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, phone 0345 464 0079 or drop us an email.

When to call us in Sulham
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, so it tears when the joint moves. Backing sets the depth and stops that.
Most people get in touch when they notice something like this:
- Repeat leaks from the same joint
- A second bead peeling off the first
- Smears and lumps from a botched reseal
- Sealant that came away because the surface wasn’t prepared
In the older streets around Church of St Nicholas, walls and floors in older homes can move, and sealant and grout show it first.
What to look for in a quote
- Who turns up on the day
- How long to leave it before use
- The length of the guarantee
- How hidden problems are handled
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Tiles that have come away from the wall
- Sealant in an older building that needs testing for asbestos first
- A bath, tray or worktop that moves until it’s properly fixed
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before you book.
What we seal
- Expansion joints
- Leaking tray & enclosure joints
- Failed movement joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Mouldy bath & shower sealant
Surface by surface
Mouldy bath & shower sealant
Repeat mould normally points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath, and then we reseal it neatly.
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most joints, depending on how much old sealant has to come out. In a small place like Sulham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
