How commercial sealant contractors works in W5
Sometimes a split bead is a symptom rather than the cause. Water at a window perimeter might be coming from the frame, the cill or the wall behind, and repeated splits in a movement joint can mean the joint is too narrow for the movement. Part of the job is telling you when the fix is something other than sealant. The enquiries we see most involve a top-up bead over failed sealant, now lifting and mouldy silicone around WCs, urinals and vanity tops, on floor and threshold joints, kitchen worktops and splashbacks and washrooms and tea points.
We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it.
- You send photographs, drawings or a list of the joints and areas involved.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Before anything is cut out, we agree access, timings and sequence.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.

Around Ealing
In Ealing, that means premises near Library for Iranian Studies, Great Ealing School and Christ the Saviour Church of England Primary School. Also close by are Ealing Independent College (under half a mile north), St Saviour's Church (less than half a mile east), Walpole Park (under half a mile north-east) and The Red Lion pub (less than half a mile south-east). The nearest railway station is Ealing Broadway station, roughly 0.5 miles north-east. A little further out are London Designer Outlet (3.3 miles north) and Gunnersbury Park House - Large Mansion (1.2 miles south-east). The countryside around Ealing includes Castlebar Hill and Middle Lake.
Shops, offices and hotels in W5
From Ealing, Brentford and Northfields outwards, W5 has a broad spread of commercial premises: shops, offices, hotels, restaurants and units. We cover the whole area, so occupiers with several sites can use one contractor and one point of contact.
The South East is one of the UK’s drier regions, though outside work in W5 still waits for dry faces, and cold mornings bring frost and condensation on steel and glass.
Ealing: In a retail centre such as Westway Shopping Park, 2.5 miles north-west of Ealing, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish. In hotels such as Hotel Xanadu, less than half a mile north-east of Ealing, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.
General trades versus a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What sets the cost
Quotes vary with the job. It mainly depends on:
- How much existing material needs removing
- Working within restricted access windows
- Joint width, depth and condition
- Any access equipment needed
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Any dates the work must fit around
- The asbestos register, for older buildings
- Photos of the joints, close up and from further back
- Where the site is, with the postcode
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Leave it or put it right?
It can be tempting to hold sealant work back until the next refurbishment. For internal joints that are only cosmetic, that can make sense, but a joint letting water in now keeps doing damage until the refurb arrives. We can seal the urgent joints now and leave the rest for the programme.

Signs you need commercial sealant contractors
Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath. By the time it shows, there can be two or three layers to cut out.
It’s worth sending us details if you spot any of the following:
- Water staining near frames, panels or ceilings
- Frame sealant that has cracked, shrunk or pulled away
- Mouldy silicone around WCs, urinals and vanity tops
- External beads that have gone brittle and cracked
Building owners, agents and FMs in W5
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in W5 can sit alongside others in a wider programme.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
FAQs: W5
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you work directly for building managers?
Yes. You can send details through our quote form, and we’ll confirm any paperwork you need with the quote.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
