Remedial sealant for homes and businesses in Aithsetter
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you email us at info@mrmastic.co.uk, and say how long ago it was last done. Common call-outs are for decorators’ caulk around a bath or shower and dark patches showing through the sealant, on expansion joints, shrunken worktop sealant and botched or over-sealed joints.
In and around a place like Aithsetter, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are usually the first signs.
Our work is backed for twelve months.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
If you manage several properties in or around Aithsetter, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.
Surface by 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 before backing and resealing.
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. We will reseal and tell you if extraction looks to be the issue.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Cracks in the fitting rather than the joint
- Plumbing leaks behind walls or under trays
- Sealant in an older building that needs testing for asbestos first
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before you book.
Surfaces we seal
- Failed movement joints
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Expansion joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
Why deal with it now?
Remedial work takes longer than a straight reseal, but rarely a lot: it takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. Around Aithsetter, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Can I do it myself?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Can you fix a reseal that hasn’t worked?
Yes, usually. First we check whether the leak is the sealant at all, then strip and reseal the joints.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before work begins.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep movement joints clear of mortar and paint
- Look for stains below bathrooms now and then
- Have loose fittings fixed before resealing
- Deal with small splits early
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. Outdoor work around Aithsetter depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
