Can you work around term dates at a campus such as Middlesex University?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you take on small jobs?

About our washroom sealing in Elstree
In healthcare and care settings, sealing is part of keeping surfaces cleanable. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Any records you need are confirmed with the quote. The enquiries we see most involve a new bead over an old one coming away and split or peeling sealant at shower trays, on kitchens and tea points, urinals and WCs and showers, trays and wet room floors. Searching for sealant specialists in Elstree? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Halls and community buildings near places like Elstree are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What happens if it’s left?
Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Older rural buildings around Elstree move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

What we are called out for in Elstree
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water and they discolour and fail early.
It’s worth sending us details if you spot any of the following:
- Failed joints along IPS and cubicle panels
- Mould spotting along silicone joints
- Users noticing mouldy joints
- Shower tray joints that have opened up
At a hotel such as Manor Hotel, 0.5 miles south-east of Elstree, the quieter weeks are the time to reseal bathrooms.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- How they’ll work around occupants
- Who will actually carry out the work
- Will RAMS and insurance details be available?
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Water escaping beneath the floor rather than through a joint
- Swollen or delaminated boards behind panels or vanity tops
- A dripping waste or valve behind a panel
Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly.
What we seal
- Urinals and WCs
- Accessible toilets and changing rooms

What sets the cost
Quotes vary with the job. It mainly depends on:
- Any access equipment needed
- The site’s rules and procedures
- Removal of failed or old sealant
- The total length or number of joints
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

A few photos plus some basic facts will normally do. It helps to include:
- When you need the work done
- Access details, including height
- Specification clauses that apply
- Whether the building will be occupied during the work
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Diagnose, treat, sign off

Advice
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Clear standing water from shower floors where possible
- Note failing joints building by building
- Leave signs up until the cure time is over
- Report split joints at trays and basins early
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.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.
