Commercial sealant around Norcott Hill
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you look after a church, hall or community building such as Church of Saint Mary, any kitchen and washrooms need the same sealant care as any other building. If you look after a building such as St Mary's CofE Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Quotes for commercial sealant in Norcott Hill
Jobs vary more than people expect. What affects the quote:
- The old material and how stubborn it is
- How easy the joints are to reach
- The product the joint needs
- Any working-time requirements on site
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
Helping us quote
To make quoting easier, let us know:
- Pictures of the joints, sent by email
- The problem you’ve noticed
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To get started, ring 0345 464 0079 or drop us an email.
Norcott Hill questions
I let a flat near Tring station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Is Norcott Hill within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Does commercial work come with a guarantee?
Yes, with our 12-month guarantee. Regular gentle cleaning and working extraction help the sealant last.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
For landlords and businesses
Landlords and agents in Norcott Hill can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Log resealing so you know what’s due
- Report broken fans quickly
- Encourage users to squeegee shower walls
- Tell cleaning staff when each room can be used
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.
Different surfaces, different methods
Rental portfolios
For a portfolio, we can quote several addresses together, with each one done when access suits.
Hotel bathrooms
In a hotel, every bathroom is used and cleaned daily, so joints are finished smooth and sealed with anti-fungal sanitary silicone.
How the visit works
We keep the work tidy and contained to the joints we’re treating. The job usually takes anything from a few hours to several days, depending on the number of rooms, and we explain the cure time before we leave. In a small place like Norcott Hill, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we visit and agree the scope, the sequence and the working hours.
- Each area is protected and the old sealant cut out completely.
- The joints are degreased, treated and left to dry.
- New sealant suited to each area is applied and tooled.
- We check every room and give its cure time for housekeeping.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
