What else we do in North End
Leave it or put it right?
Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. Replacement deals with the cause in the joint and your cleaning team stops chasing it. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Make sure washroom ventilation is running
- Note failing joints building by building
- Tell us about infection-control or permit rules before we quote
- Inspect washroom sealant regularly
Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.
Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job with more phasing to plan.
Washroom sealing around North End: how the place shapes the job
North End is within about 1 mile of the coast, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Washrooms used guest after guest wear their sanitary silicone faster, so resealing in the quieter months keeps rooms ready. Two care or nursing homes sit less than 2 miles from North End. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. We plan the work with the manager so residents are disturbed as little as possible.
Colleges such as Portsmouth College, 1.6 miles to the east of North End, have toilets, changing rooms and catering kitchens that can be resealed around term dates. Customer toilets and staff facilities at retail sites such as Victory Retail Park (to the south-west of North End) need sealant that stays clean under heavy use. Student showers at universities like University of Portsmouth - North Zone (1.5 miles south-west of North End) see more use than most, and their silicone shows it.
North End is about 1 mile north of Portsmouth, in Portsmouth. Any commercial site in North End is covered, whether it’s a single job or part of a planned programme. We work across 19 places in Portsmouth.
Business premises anywhere in PO2 and PO1 are within our area for washrooms and wet areas. Among the streets we cover are Knox Road, Croft Road and Kirby Road, and sites on any of them can send details for a fixed quote. Main routes into North End include the A2047. Nearby places we also cover include Rudmore (1 mile south-west), Tipner (1 mile west), Portsmouth (1 mile south), Copnor (1 mile south-east) and Hilsea (1 mile north-east).
What’s near North End
Locally, jobs take us to sites close to Mayfield School, Alexandra Park and St Edmund's Catholic School and the streets around them. North End’s nearest station is Hilsea station, about 1.2 miles north-east of the centre. Other landmarks nearby include Charles Dickens Birthplace Museum (0.8 miles south-west) and Portchester Castle (2.1 miles north-west). Green spaces nearby include Portsdown Hill and Milton Locks.
What affects the price in North End
We price every job individually. The things that drive the figure:
- Joint width, depth and condition
- Phasing around occupants
- How much there is to seal
- Location, for remote and island sites
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.
What to include in your enquiry
A few photographs plus some basic facts will normally do. Please tell us:
- How the joints are reached, and at what height
- The site address and postcode
- When you need the work done
- The asbestos register, for older buildings
To get a fixed quote, give us a call on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.
General trades versus a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Questions we are asked in North End
Is North End too small for you to travel to?
Not at all. North End is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you take on work at healthcare sites like St James Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Can you clean the mould off instead of resealing?
Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
Will all the toilets be closed at once?
The work is phased so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we will plan around them.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
