Mastic sealing across Nash Lee
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
General trades versus a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
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.
Mastic sealing in Nash Lee, done properly
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. The enquiries we see most involve estate-wide sealant that is simply worn out and cracked, hardened mastic round windows on a block, on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints. One point of contact handles commercial sealant work in Nash Lee from the first photos to the final walk-round, for single jobs and planned programmes alike.
For owners with a single building near Nash Lee, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Planned mastic for Nash Lee portfolios
Nash Lee is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building normally need attention first. Nash Lee has two care or nursing homes no more than 2 miles away. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
If you look after a block within reach of Stoke Mandeville station, 1.4 miles north of Nash Lee, frame and balcony mastic can be renewed on one programme. Trustees of buildings like Church of St Peter and St Paul can bring frame and external mastic into a planned maintenance list.

When to call us in Nash Lee
Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one it comes away from one face.
Any of the following is a good reason to get the joints checked over:
- Failed external movement joints
- Patchy repairs in mismatched sealant
- Mastic failing across several blocks on an estate
- Cracked, hardened mastic round windows on a block
For owners of several units at places like Station Approach Business Park (1.3 miles east of Nash Lee), one programme can deal with frame and external mastic across the lot.
What to look for in a quote

- The named product and why it was chosen
- Whether old or failed sealant will be cut out, not overlaid
- How joint depth will be controlled
Keeping the joints sound
Once the work is signed off, these steps help:
- Log resealing dates block by block
- Keep bins and bikes away from communal door frames
- Have the asbestos survey to hand for older buildings
- Plan resealing building by building rather than complaint by complaint
Keep records of when each building was resealed. It helps plan the next round and shows what was done.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

Advice
Cost factors for mastic joints
We price every job individually. The things that drive the figure:
- How much there is to seal
- How much existing material needs removing
- Backing rod, priming and other preparation
- Working within restricted access windows
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- Your programme or deadline
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
- Any specification or named product
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Questions we are asked in Nash Lee
We manage a building near Stoke Mandeville station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Can work in a care setting near Nash Lee go ahead while residents are there?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
How long does a job like this take?
That varies with the scale of the job, but the work normally takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
