What remedial sealant looks like in Aylesbury
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings. There are hotels and other places to stay in and around Aylesbury. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For an older house near a landmark such as Church of St Mary, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Managing a site like Buckinghamshire UTC? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What else we do in Aylesbury
Why deal with it now?
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. For landlords in Aylesbury, failed sealant soon turns into tenant complaints about mould, damp or draughts. Sorting it between tenancies is easier than dealing with it mid-let.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
Why choose Mr Mastic in Aylesbury
- You choose the colour before work begins
- Anti-fungal silicone where joints get wet
- Every job guaranteed for a year
- We leave the area clean and tidy
What the job involves on each surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned.
Aylesbury: your questions answered
Do you take on hotel work around Aylesbury?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
I let a flat near Aylesbury station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you cover Aylesbury?
We do. Aylesbury is part of the area we cover, and the service is the same as everywhere else.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
What if resealing will not fix my leak?
In that case, we tell you what we’ve found. You may need a plumber or bathroom fitter.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What we do, step by step
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for most joints, depending on how much old sealant has to come out in most cases. For homes and businesses in busier parts of Aylesbury, parking needs a little planning. Let us know about stairs, lifts or shared entrances too.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us about any water getting in
- Mention any parking rules near the property

Signs you need remedial sealant in Aylesbury
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing sets the depth and stops that.
Keep an eye out for these signs:
- Movement joints that have split or pulled away
- Leaks that keep coming back after resealing
- Worktop sealant that has shrunk and split
- Black mould underneath the bead
For landlords with property near Aylesbury station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Questions to ask before booking
- What the cure time is
- Who turns up on the day
- What product goes in the joint
- How the joint is cleaned and prepared
Aftercare tips
After the cure time, these simple habits help:
- Do not add new sealant on top of old
- Ask why a joint failed before redoing it
- Use a soft cloth, not a scourer, on silicone
- Run the fan after every shower
Where we have pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Sealant in an older building that needs testing for asbestos first
- Failed tanking or loose tiles behind the sealant
- A cracked shower tray or bath (that needs repair or replacing)
If in doubt, call 0345 464 0079 or email us and we will say what we think.
What we seal
- Mouldy bath & shower sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Expansion joints
- Shrunken worktop sealant
- Botched or over-sealed joints
Landlords, agents and businesses in Aylesbury
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
