Sealant applicators in Nether Street
A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Primer is used wherever the manufacturer calls for it on that surface, and a backing rod limits the depth to give the sealant room to work. If you’re dealing with sanitary sealant that has gone black and patchy and weathered facade sealant that no longer flexes, we can help, on floor and threshold joints, external facade joints and movement joints in walls and floors alike. Whoever orders the work in Nether Street, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Multi-site clients with buildings in and around Nether Street can put several sites on one programme, with one quote format and one point of contact.
Rural business units near smaller places such as Nether Street are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.
A 12-month guarantee applies to all our work in Hertfordshire. If an installation problem shows up, give us a call on 01277 525 020 or use the quote form and we will arrange a return visit.

When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Leaks from pipework, wastes or valves (that’s plumbing)
- Faulty windows rather than failed perimeter sealant
If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer.
Joints and surfaces we work on
- Washrooms and tea points
- Movement joints in walls and floors
- Kitchen worktops and splashbacks
- Floor and threshold joints
- External facade joints
- Window and door perimeters
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. Splitting the scope into now and later is often the sensible compromise. One visit to deal with every failing joint makes more sense than several trips to a place like Nether Street. Send photos of each area and we will quote for the lot.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Your questions answered
Is a smaller place like Nether Street outside your area?
Not at all. Nether Street is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Does your area include sites such as Home Farm Industrial Park, near Nether Street?
Yes. We cover Nether Street and the area around it, including industrial estates, business parks and retail parks such as Home Farm Industrial Park. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you supply RAMS and insurance details?
The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Our applicators are CSCS-carded.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you take on multi-site sealant work?
Yes, across South East England, Greater London and all of Scotland. One contact and one process for every building makes a portfolio easier to manage.
Is the old sealant taken out first?
Every scrap of failed sealant is removed before the new bead goes on. Sealing over traps water and lifts once the joint moves and isn’t worth paying for.

Sealant on show in Nether Street’s commercial buildings
Rainfall across the South East, Nether Street included, is lower than in many parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Nether Street is about 24 miles from central London. This part of the South East is dense with business parks and out-of-town offices. Firms with branches across the South East can use one contractor for every site.
Industrial estates such as Home Farm Industrial Park (to the south-west of Nether Street) have offices, trade counters and welfare areas whose sealant ages like any other building’s. Shops and cafés around stations like Harlow Town station (to the south of Nether Street) trade from early, so work is timed around them.

Different surfaces, different methods
Facade and cladding joints
Panel joints on cladding and rendered facades open and close with the temperature. They need a sealant with the right movement capability, laid at the right depth. We confirm the access in place before we quote.
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, and tell you if the edges need repairing first.
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 work around Nether Street, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First, details come to us: photographs, drawings or a schedule of the areas, or we arrange a site visit.
- Next comes a diagnosis and a fixed quote.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
What we need from you
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work
- Move anything stored against the joints

How the quote is worked out
The price varies from site to site. It mainly depends on:
- Distance, for remote addresses
- How accessible the joints are
- Working within restricted access windows
- The size and state of each joint
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What we need to price the job
A few photographs plus some basic facts will normally do. It helps to include:
- Any dates the work must fit around
- A wide shot and a close-up of the area
- Any specification or named product
- Whether the building will be occupied during the work
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, ring 01277 525 020 or email a schedule or drawings.
