Commercial sealant contractors across N19: what to expect
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. We look before we quote and tell you plainly if sealant won’t solve it, so nobody pays for a reseal that can’t hold. Site teams most often ask us about mouldy silicone around WCs, urinals and vanity tops and smeared sealant across finishes from a rushed job, on washrooms and tea points, window and door perimeters and external facade joints.
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
What you will pay
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What you get with us
- CHAS accredited
- A range of standard colours, depending on the product
- CSCS-carded applicators

What’s near Upper Holloway

Other local landmarks include City of London Academy (less than half a mile north-east), The Mother Red Cap pub (less than half a mile north-west), Asanté Academy of Chinese Medicine (1.2 miles north-west) and Vaughan Williams Memorial Library (2 miles south).

Where commercial joints are in N19
The commercial stock in N19 mixes older town-centre buildings with newer offices and units, in places such as Holloway, Upper Holloway and Nag's Head and beyond. Each building needs the right product for its surfaces, from stone and brick to coated aluminium and laminate.
London and the South East are among the drier parts of the UK, though outside work in N19 still waits for dry faces, and cold mornings bring frost and condensation on steel and glass.
Upper Holloway: For premises near Upper Holloway station, less than half a mile to the south-east of Upper Holloway, footfall is part of the plan: work is phased so shops and offices keep trading. On estates like Bush Industrial Estate, which lies south of Upper Holloway, the office and welfare end of each unit has its own sealant to maintain.
Quoting for work in N19
The price varies from site to site. Expect it to depend on:
- Working within restricted access windows
- Access and working height
- Location, for remote and island sites
- The product specified
The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- How the joints are reached, and at what height
- The product your specification calls for
- The postcode of the building
- A wide shot and a close-up of the area
For a fixed quote, phone 01277 525 020 or email the details over. Our quote form is another easy route.
Common problems we fix in N19
A split down the middle of the bead tells a different story. Usually the movement was too much for the sealant chosen: a bead laid too thin, an over-stretched joint or the wrong movement class. The same product in the same joint tends to fail the same way.
What tends to prompt an enquiry:
- Untidy joints in a reception, shop floor or lobby
- Greasy, split joints in a kitchen or tea point
- Layers of sealant, all of them failing
- Expansion joints with the sealant torn out
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, 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.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Walls or slabs moving more than any sealant can take
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
For managing agents and facilities managers
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in N19 can sit alongside others in a wider programme.
FAQs: N19
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Do you take on multi-site sealant work?
Yes. We regularly take on multi-site work and planned maintenance programmes.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
