How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. For a job in Owlsmoor, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

Advice
Remedial sealant in Owlsmoor, done properly
A joint that keeps failing normally has a reason. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. Finding that cause comes before any new sealant. We work on mouldy bath & shower sealant, leaking tray & enclosure joints and botched or over-sealed joints, and the jobs we see most are wide, uneven beads that look worse than the old ones and worktop sealant that has shrunk and split.
In a smaller place like Owlsmoor, homes are mostly houses and bungalows rather than flats, some older and some much newer. Sealant and grout wear out here just as they do in a big town.
There’s a 12-month guarantee on every job, large or small.

Why deal with it now?
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. Around Owlsmoor, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

What the job involves on each surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is normally part of the cause. We will reseal and tell you if extraction looks to be the issue.
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath, then reseal neatly.
How we quote for remedial sealant
Call for a quick quote. The main things that affect it are:
- How many areas need sealing
- Mould in or behind the old joints
- The number and length of the joints
- Working hours on commercial sites
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- Any access issues, like height or stairs
- The address or postcode of the job
- Pictures of the joints, sent by email
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or drop us an email.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, 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.

Owlsmoor: your questions answered
I let a flat near Sandhurst station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Owlsmoor?
Yes, Owlsmoor is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How long should I leave it?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. First we check whether the leak is the sealant at all, then strip and reseal the joints.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Can you remove sealant that is been put over old sealant?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
What we’re called out for in Owlsmoor
A lot of failed joints have been sealed over rather than replaced. Silicone does not bond to silicone, so the top layer lifts and water and mould collect between the two.
Any of these means the joints need attention:
- Kitchen joints letting water behind the worktop
- Sealant applied over old sealant that has lifted
- Caulk or the wrong sealant used in a wet area
- Leaks that keep coming back after resealing
In the older streets around St George's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What to look for in a quote
- Is the old sealant removed completely?
- What guarantee comes with the work
- What product goes in the joint
- Is VAT in the price?
What remedial sealant looks like in Owlsmoor
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you let a flat or house near Sandhurst station, a joint that keeps failing is best fixed properly while the property is empty. Schools such as Owlsmoor Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
