Facade sealing for commercial buildings in Nash
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear. We work on shopfront frames, coping and flashing joints and window and door perimeters, and what we are called in for most is patch repairs that keep failing and staining on stone next to old sealant. Most enquiries from Nash start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Around Nash, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

For managing agents and facilities managers
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Nash can sit alongside others in a wider programme.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Nash: questions and answers
Can you work at a site such as Glebe Farm Business Park, by Nash?
Yes. We cover Nash and the area around it, including industrial estates, business parks and retail parks such as Glebe Farm Business Park. To start, just phone 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Can you take on a job at a hospital such as Princess Royal University Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you provide access for facade work?
Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we’ll price the work around it.
How do you choose the sealant?
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.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs usually get a visit.
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 fixed quote.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Leave it or put it right?
Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once, which is often the biggest saving. Failed sealant in a building in Nash can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Building and refurbishing in Nash
As part of Greater London, Nash is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
Recladding or extending a unit at a site like Glebe Farm Business Park, 1 mile to the south-east of Nash, brings panel joints and frame perimeters into the programme. With historic properties like Down House (to the south-east of Nash) in the area, refurbishment work often meets old masonry that needs compatible sealants. When a college such as Shaftesbury Nash College (to the north of Nash) builds or refurbishes, the mastic package typically has to fit around students and staff.
