Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building around Nup End Green, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Before we start on site
- Send any specification or drawings in advance
- Point out parking and an unloading spot
- For older buildings, check the asbestos register before work

What affects the price in Nup End Green
To price the job, we consider:
- Whether the work must be split into stages
- The product specified
- Whether old sealant has to be cut out first
- Distance, for remote addresses
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- How the joints are reached, and at what height
- Clear photos of the problem areas

- Approximate linear metres or a joint schedule

Common questions from Nup End Green clients
Is Arlington Business Park, near Nup End Green, within your area?
Yes. Our area takes in Nup End Green and its surroundings, with estates and business parks such as Arlington Business Park included. Photos and a short description are enough for a first look.
Can you work around term dates at a campus such as North Hertfordshire College - Stevenage Campus?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you replace failed glazing units?
No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Damp caused by condensation inside the building
- Specialist high-level access methods
- Cracked or spalling substrates that need repair before sealing
If in doubt, call 01277 525 020 or use the quote form and we will say what we think before you book.
Joints and surfaces we work on
- Coping and flashing joints
- Stone and brick facade joints

Facade sealing around Nup End Green: how the place shapes the job
Rainfall across the South East, Nup End Green included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. At about 26 miles from central London, Nup End Green is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
For contractors at a college like North Hertfordshire College - Stevenage Campus, 2.3 miles north of Nup End Green, perimeters and internal sealant are timed for the holidays. For contractors refurbishing units at places like Arlington Business Park, 1.8 miles north of Nup End Green, the mastic covers cladding panels, roller-door and window perimeters. Hospital estates such as Lister Hospital, 4.1 miles to the north of Nup End Green, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
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.
Why it’s worth doing now in Nup End Green
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. Halls, stores and units around places like Nup End Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
