About commercial sealant contractors in EC1N
Pricing a commercial reseal is a short process. Our quote form takes photos, drawings or a schedule of the areas and you can also ring 01277 525 020 or send details through our quote form to talk it through. Where the photos don’t tell the full story, we arrange a site visit, and a fixed quote for the agreed scope follows. We work on window and door perimeters, movement joints in walls and floors and external facade joints, and the usual reasons a site gets in touch are greasy, split joints in a kitchen or tea point and frame sealant that has cracked, shrunk or pulled away.
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area.
- We start with the evidence: photographs, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.

Commercial sealant contractors across EC1N: the area picture
Across EC1N, from Blackfriars and Temple Bar to the smaller places between, commercial buildings run from high-street shops and offices to hotels, schools and business parks. We cover the whole area, so occupiers with several sites can use one contractor and one point of contact.
The South East has large numbers of business parks and industrial estates, especially around the motorway corridors, and EC1N is part of the area we cover.
Blackfriars: In a retail centre such as Brunswick Centre, 1.2 miles north-west of Blackfriars, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish. Occupiers with premises at both Grand Vitesse Industrial Estate and Southwark Bridge Business Centre could have the sealant at each handled under one quote.
Surface by surface
Movement joints in walls and floors
A trafficked floor joint needs a different product from a wall joint. The choice comes down to how much the joint moves and what runs over it; if the arrises are broken, we’ll say so before sealing.
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead.
After the work
For the best life from the joints:
- Check the asbestos register before anyone disturbs old sealant in an older building
- Check sealant as part of routine building inspections
- Respect the cure time before reopening an area
- Report cracked or peeling sealant early
In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, and mould follows damp. Your maintenance team can look at extract fans at the same time.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.
Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What happens if it’s left?
Reactive resealing, a leak at a time, tends to cost more overall than a plan. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We’ll suggest an order, worst sealant joints first.
Questions to ask before you book
- Will failed sealant be removed rather than covered?
- Health and safety accreditation such as CHAS
- Do they follow the manufacturer’s priming guidance?
- Will RAMS and insurance details be available?
Cost factors for sealant joints
Before we quote, we look at:
- How much there is to seal
- Distance, for remote addresses
- How much existing material needs removing
- Which sealant the job calls for
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- Access details, including height
- The postcode of the building
- Drawings or a marked-up plan, if available
- Your programme or deadline
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
EC1N: questions and answers
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Can one contractor look after sealant on all our buildings?
Yes, within the areas we cover: South East England, Greater London and Scotland. Each site gets the same process and a single contact.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
How many days will you need on site?
It depends on the scope, though a typical visit normally takes a few hours for one area, or a planned series of visits across a bigger building. For bigger or phased jobs, we will set out a timescale with the quote.
Which site documents can you send us?
We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
Do you work for facilities managers and managing agents?
Yes. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.
Does commercial sealant work come with a guarantee?
Our workmanship on each job is backed by a 12-month guarantee. We’re fully insured for public liability as well.
