How we handle remedial sealant in Merrow
Remedial jobs in Merrow normally fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. We work on mouldy bath & shower sealant, failed movement joints and botched or over-sealed joints, and common reasons people get in touch are gaps opening along the back of the worktop and torn expansion joints.
Even in a smaller place like Merrow, bathrooms and kitchens see heavy daily use. Older or newer, every room gets the same approach: all the old material out, the joint cleaned and dried, then new sealant or grout.
Every job is covered by a 12-month guarantee.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Merrow homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Clandon station? Then a joint that keeps failing is best fixed properly while the property is empty. For site and facilities teams at buildings such as Bushy Hill Junior School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Common problems we fix in Merrow
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
Look out for any of the following:
- Decorators’ caulk around a bath or shower
- Sealant that came away because the surface wasn’t prepared
- Thick, messy sealant smeared over tiles
- Movement joints that have split or pulled away
For an older house near a landmark such as Church of St John the Evangelist, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
Questions to ask before you book
- Are they insured?
- Is the old sealant removed completely?
- What happens if they find a problem under the old sealant
- How long to leave it before use
How the visit works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours, depending on how many layers have to come out. A visit to Merrow is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit

What the job involves on each surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before any new sealant goes on.
Why it’s worth doing now in Merrow
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. In an older home around Merrow, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email.

What affects the cost of remedial sealant
We don’t publish a price list, because no two jobs are the same. What we look at:
- Any working-time requirements on site
- The amount of work
- Whether there’s mould to deal with
- Whether the work is at height
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Questions from Merrow
Can you help a landlord with a rental near Clandon station?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Merrow?
Yes. Merrow is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can failed expansion joints be resealed?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
What if resealing will not fix my leak?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
How long should I leave it?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Have loose fittings fixed before resealing
- Get the cause of a repeat leak found before resealing
- Do not point over movement joints
- Keep bleach and abrasives off the bead
Where we have pointed out another fault, have it put right, or the new joint may fail again.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
