Remedial Sealant in Reston

- Mould trapped under a layer of silicone
- Repeat leaks from the same joint
- Kitchen joints letting water behind the worktop
Why deal with it now?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Around Reston, water from a failed joint in an older stone home can soak into timber and plaster.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
What you get with us
- Any old sealant cut out fully, not covered over
- Arbo and Everbuild products

- White, clear, grey or another colour, product permitting

Remedial sealant in Reston
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you’re dealing with torn expansion joints and sealant that came away because the surface wasn’t prepared, we can help, whatever the surface.
Being further from a city does not change the work: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. We just plan the journey and access beforehand.
You are covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
How the visit works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. Outdoor work around Reston depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

Advice
When to call us in Reston
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. At that point it has to come out.
Keep an eye out for these signs:
- Smears and lumps from a botched reseal
- Beads that never stuck properly
- Black mould underneath the bead
- Repeat leaks from the same joint
If you let a flat or house near Reston station, a joint that keeps failing is best fixed properly while the property is empty.
What your quote should include
- Is VAT in the price?
- What the cure time is
- Whether the sealant suits the joint
- Is the old sealant removed completely?
Bathrooms and kitchens in Reston
Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
In the older streets around Reston Church Of Scotland, older homes can move a little, which is hard on rigid grout and tired sealant.

Looking after it afterwards
So the new joints stay in good condition:
- Have loose fittings fixed before resealing
- Clean sealant with mild products only
- Find out why the sealant failed first
- Do not wait for a small gap to become a leak
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.
Reston questions
Can you help a landlord with a rental near Reston station?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.

Yes. Our work covers the whole of Scotland, and Reston is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
What if the leak is not the sealant?
In that case, we tell you what we have found. A plumber or fitter may be needed before any new sealant goes on.
Can you quote for more than one area?

Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before work begins.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
