- A shower tray, bath or basin that’s cracked or broken
- Certifying fire stopping or building compliance

What affects the quote in Waterlooville
We don’t publish a price list, because jobs vary so much. What we look at:
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- The size of the job
- How many rooms, windows or areas are involved
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- The type of property
- Any previous sealing or DIY work
- Roughly how big the job is
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand.
What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes as long as the scope needs, from one welfare room to a full building. In Waterlooville, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First we visit and agree the scope, the sequence and the working hours.
- Room by room, we protect the area and remove all the old sealant.
- The joints are degreased, treated and left to dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- We check every room and give its cure time for housekeeping.
Before we arrive
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on

Your questions about commercial sealant in Waterlooville
Can you do commercial sealant in Waterlooville?
Yes, Waterlooville is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Is there a guarantee on commercial sealant in Waterlooville?
All our work, in Waterlooville and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you reseal between tenancies?
Yes. A planned programme across a portfolio keeps things simple, fitting around access to each property.
Can you reseal every bathroom in a hotel?
Yes, we can. We work through big sites room by room or floor by floor, keeping most of it in use.
Where are you based?
Mr Mastic is based in Crawley. We cover Waterlooville and the rest of Hampshire, along with the rest of our area.
What commercial sealant looks like in Waterlooville
If you run a hotel, guest house or holiday let in a coastal place like Waterlooville, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Community buildings like Saint George's are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. Letting a property close to Bedhampton station? Then we can quote for one property or a whole portfolio of rentals.

What else we do in Waterlooville
Surface by surface
Hotel bathrooms
Hotel showers and baths get used and cleaned every day, so joints are finished smooth and sealed with anti-fungal sanitary silicone.
Student & care accommodation
Empty rooms between terms or tenancies are easy to reseal, but occupied rooms can be planned in as well.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What we are called out for in Waterlooville
Shower trays and baths in busy buildings move more: different weights, constant use and daily cleaning all work at the joint. If a tray flexes, the sealant around it splits.
The problems people usually mention when they call are:
- Too many rooms to reseal without closing the building
- Leaks from showers into rooms or ceilings below
- Black, stained silicone in guest bathrooms
- Split sealant where wet room floors meet walls
Schools such as Hart Plain Junior School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.
Questions to ask before you book
- How long the guarantee is
- Which sealant they’ll use, and why
- How hidden problems are handled
- How the surfaces are prepared before sealing
