About our construction mastic in Up Nately
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over. Sealing too early only means coming back once others have damaged it. We work on cladding and panel joints, window and door perimeters and sanitary and kitchen joints, and the usual reasons a site gets in touch are failed sealant in an existing building being refurbished and cracks opening in caulked internal joints. A single leaking joint is often how a building in Up Nately first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Sites around smaller places like Up Nately can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Different surfaces, different methods
Window and door perimeters
Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.
Why it’s worth doing now in Up Nately
Sealing over damaged or contaminated new joints might save a day. New sealant laid on old or dirty sealant has nothing to bond to. We cut out and redo the joint properly. Converted and older buildings near places like Up Nately tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Is a smaller place like Up Nately outside your area?
Not at all. Up Nately is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Will you stick to the specified products?
We use the product the specification names. Any suggested alternative is put to you before anything changes.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Tell us what records you need and we will confirm with the quote.
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off.

Common problems we fix in Up Nately
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Common reasons buildings call us in:
- A long mastic snag list close to completion
- Caulk cracking where joints are moving more than expected
- Early adhesion failures on new external joints
- Missed perimeter joints on a new elevation
On a healthcare site such as Basingstoke and North Hampshire Hospital (5.2 miles west of Up Nately), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Building and refurbishing in Up Nately
A number of hotels sit less than 2 miles from Up Nately. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. Up Nately is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
Units on estates such as Hatch Industrial Park, 1.6 miles west of Up Nately, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. When a school such as Robert May's School is extended or refurbished, the mastic package is often squeezed into the holidays.

Quoting for work in Up Nately
Each job is priced on its own details. The things that drive the figure:
- The total length or number of joints
- Which sealant the job calls for
- Travel to remote or island sites
- Phasing around occupants
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.
What to include in your enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
- The product your specification calls for
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
