Need washroom sealing in North Mundham?
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
After the work
A few simple habits keep the new joints working:
- Share your site rules when you send details
- Inspect washroom sealant regularly
- Keep a record of which washrooms need attention
- Clean sealant with gentle products and a soft cloth
Include sealant joints in your planned maintenance checks. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.
Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.
Washroom sealing in North Mundham
You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. If you have urinal joints that look unhygienic and complaints from staff, guests or users about tired washrooms, we can put it right. Searching for sealant specialists in North Mundham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Farm shops, cafés and venues in converted rural buildings around places like North Mundham have busy toilets and kitchens. Tell us your opening times and quiet periods and we will plan around them.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Vanity carcasses that have swollen
- Failed tanking beneath a wet-room floor or behind tiles
Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly before you book.

What else we do in North Mundham
How the quote is worked out
A fixed quote reflects the actual work. It takes account of:
- Site requirements such as inductions and permits
- Backing rod, priming and other preparation
- Whether old sealant has to be cut out first
- The total length or number of joints
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What we need to price the job
Good information means a firmer quote. Helpful details to send:
- Drawings or a marked-up plan, if available
- The site address and postcode
- Clear photographs of the problem areas
- Any dates the work must fit around
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email drawings and photos if you’d rather talk the job through.

North Mundham: questions and answers
Does a hotel in North Mundham need to shut while its sealant is renewed?
Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we’ll plan around them.
Do you take on work at healthcare sites like St Richard's Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is there a guarantee on the work?
Our workmanship has a 12-month guarantee, and we carry public liability insurance.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near North Mundham need work, visits can be combined. A fixed quote is given before anything starts.
- We inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- The whole of the old bead is removed.
- Joints are degreased and dried.
- New anti-mould sealant goes in and is tooled neat.
- Rooms reopen after the cure time.
Preparing the site

- Agree which areas must stay open
- Let building users know which areas are affected
Quotes
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Sanitary sealant for North Mundham buildings

Bathrooms turned round daily in the busy months need sound, cleanable joints, and the quieter months are the natural time to reseal. North Mundham has a number of hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest.
