Keills questions
Do you cover Keills for remedial sealant?
Yes, Keills is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
What guarantee comes with remedial sealant in Keills?
All our work, in Keills and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
What should I tell you?
Tell us what needs doing and where. If we need more, we will ask.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Keills, along with the rest of our area.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks generally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
How we handle remedial sealant in Keills
A joint that keeps letting you down needs more than another bead. Send photos when you email us at info@mrmastic.co.uk, along with when it was last resealed. We’re often asked to deal with floor or wall movement joints that have failed and black mould underneath the bead, across shrunken worktop sealant, failed movement joints and botched or over-sealed joints.
A bathroom in a place like Keills gets the same daily wear as one in a city flat. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
Whatever the size of the job, it’s backed by our one-year guarantee.

How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Around Keills, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Before we arrive
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Aftercare tips
To keep the joints looking good and working properly:
- Report a tray that rocks or a worktop that lifts
- Never seal over old silicone
- Check ceilings under showers for marks
- Do not point over movement joints
Where we’ve pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
Quotes for remedial sealant in Keills
We quote each job individually. These are the things that affect it:
- Any working-time requirements on site
- Whether the work is at height
- The number of rooms or windows
- The size of the job
Doing several joints on one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- Where the job is, and your postcode
Every job is quoted individually, so start by telling us what you need. Just drop us a line at info@mrmastic.co.uk with the details, and pictures are welcome.
Different surfaces, different methods
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom before resealing.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.
What we can’t put right
Before you book, it’s worth knowing the limits too:
- A tray or worktop that needs refixing first
- Tiles that have come away from the wall
- Cracks in the fitting rather than the joint
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
What we seal
- Expansion joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Failed movement joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
Signs you need remedial sealant in Keills
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
Signs it’s time to call us include:
- A second bead peeling off the first
- Black mould underneath the bead
- Wide, uneven beads that look worse than the old ones
- Leaks that keep coming back after resealing
Whether the job is in Keills itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before you book
- How much experience the applicator has
- What the cure time is
- What happens if they find a problem under the old sealant
- Which colour the sealant will be
Bathrooms and kitchens in Keills
Keills is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
Around Keills, as everywhere, remedial sealant is only as good as the preparation behind it.
