Working on commercial sites near Roe Green
Roe Green sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. Roe Green lies roughly 34 miles out from central London. The commuter belt holds a great many offices, retail parks and business parks. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.
If you run a unit on an estate such as Honeywood Industrial Centre, 2.6 miles south of Roe Green, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Offices and shops close to stations such as Ashwell & Morden station, 3.2 miles north of Roe Green, tend to be busy all day, so sealant work is planned around opening hours.
Roe Green is in Hertfordshire. Businesses, contractors and managing agents in Roe Green use us for work on sealant joints. 371 places across Hertfordshire fall within our area, Roe Green among them. London is covered too, some 34 miles away.

About our commercial sealant contractors in Roe Green
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. If you have layers of sealant, all of them failing and weathered facade sealant that no longer flexes, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Roe Green, preparation and product choice get the time they need.
A lot of what we do in Roe Green is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
Commercial sealant work around smaller places like Roe Green tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.
A 12-month guarantee applies to all our work in Hertfordshire. Should something we installed fail, give us a call on 01277 525 020 or email a schedule or drawings and we’ll come back to it.

What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Misted, cracked or failed glazing units (a glazier’s job)
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Water from a services leak rather than a joint
If you’re not sure, just call 01277 525 020 or email us and we will give you a straight answer before you book.
What we seal
- External facade joints
- Window and door perimeters
- Kitchen worktops and splashbacks
- Floor and threshold joints
- Washrooms and tea points
- Movement joints in walls and floors

Questions about Roe Green
Does your area include sites such as Honeywood Industrial Centre, near Roe Green?
Yes. Our area takes in Roe Green and its surroundings, with estates and business parks such as Honeywood Industrial Centre included. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can you supply sealant in our brand colour for a site in Roe Green?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.
How long does a job like this take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Could the old sealant in an older building contain asbestos?
It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards.
Is failed sealant stripped out, or sealed over?
Every scrap of failed sealant is removed before the new bead goes on. Sealing over traps water and lifts once the joint moves, so it isn’t something we do.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
From enquiry to sign-off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Roe Green need work, visits can be combined. You will have a fixed quote before work starts.
- 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.
- The failed sealant comes out and the faces are prepared, with primer where required.
- 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.
What we need from you
- Share the asbestos register for older buildings
- Point out any areas we must not close
- Share your working hours and any access restrictions

Advice
What else we do in Roe Green
How the job changes by surface
Facade and cladding joints
On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price, with colours confirmed for the product chosen.
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead, planned so the building keeps enough facilities in use.
How the quote is worked out
These are the things that shape the price:
- The site’s rules and procedures
- The size and state of each joint
- Whether old sealant has to be cut out first
- Travel to remote or island sites
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.
Sending details for a quote
To price the job accurately, we need a clear picture of the site. Send us:
- Whether an asbestos survey exists
- A wide shot and a close-up of the area
- What the building is and how it’s used
- Your programme or deadline
Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, call 01277 525 020 or email us.
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
