Where is Mr Mastic based?

Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can you take on a whole building?
Yes. We’ll walk the site, agree the scope and the order, and you get one clear quote.
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.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Put a squeegee in each shower
- Schedule work around occupancy
- Keep strong chemicals and scourers off the joints
- Act on lifting sealant before it leaks
Daily cleaning with harsh chemicals shortens the life of any sealant. Ask cleaners to use mild products and soft cloths on the sealant.
Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. When you see them, it’s time to plan a reseal.
Landlord and commercial work in Stotfold Common
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
What commercial sealant looks like in Stotfold Common
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For buildings such as Church of Saint Guthlac, 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 Academy Stotfold, busy washrooms and kitchens can be resealed in phases so they stay open.

Common problems we fix in Stotfold Common
In an accessible wet room, water spreads across the floor every use, so the joints at floor level are under water often. Any split there can let water through quickly.
These are the problems we’re asked about most:
- Washrooms that need sorting before an inspection
- Tired sealant in let properties
- Mouldy washroom sealant that staff and guests notice
- Sealant failing again soon after quick repairs
If you let a flat or house near Arlesey station, sealant work can be quoted for a single flat or a whole portfolio.

What happens if it’s left?
First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and scrubbing won’t fix it. Replacing it does. Around Stotfold Common, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours per room, so whole buildings are phased. For a village or hamlet like Stotfold Common, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start with a site walk to agree the rooms and the timing.
- Room by room, we protect the area and remove all the old sealant.
- The joints are degreased, treated and left to dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Rooms are checked and returned with a cure time so staff know when to use them.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
