How we handle facade sealing in Nash Mills
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. If you have weathered facade joints that have lost their grip and weathered joints at frame-to-structure perimeters, we can help, on shopfront frames, coping and flashing joints and perimeter joints where frames meet the structure alike. A single leaking joint is often how a building in Nash Mills 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.
In a smaller place such as Nash Mills, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or send photos by email and we will arrange a return visit.

Site staff or a sealant specialist?
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.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Questions about Nash Mills
Can you work on a hospital site such as Hemel Hempstead Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Does your area include sites such as Apsley Industrial Estate, near Nash Mills?
Yes. Estates, retail parks and business parks around Nash Mills, Apsley Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Can you work on upper floors?
We agree access with the client at the start. Let us know what access is in place or planned.
Is it okay to overlay old mastic?
No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.
Can the sealant be colour-matched?
It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Why it’s worth doing now in Nash Mills
Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What sets the cost
Each job is priced on its own details. The things that drive the figure:
- Phasing around occupants
- How accessible the joints are
- Backing rod, priming and other preparation
- Whether old sealant has to be cut out first
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- Any dates the work must fit around
- The product your specification calls for
- Anything awkward about access or site hours
- The postcode of the building
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Different surfaces, different methods
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification.
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.
Facade sealing around Nash Mills: points for this area
There are several hotels within about 2 miles of Nash Mills. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. Hemel Hempstead, one of the planned towns of the twentieth century, takes in or adjoins Nash Mills. Regeneration of planned-town buildings brings recladding and replacement windows, each with joints to seal.
New units and refits on sites such as Apsley Industrial Estate, 0.8 miles to the north-west of Nash Mills, need their panel and perimeter joints sealed to the specification. For contractors at a school such as Nash Mills Church of England Primary School, sealing has to be finished before term starts. When a college such as West Herts College (2.1 miles north-west of Nash Mills) builds or refurbishes, the mastic package typically has to fit around students and staff.

After the work
After handover, these steps help:
- Plan facade sealing alongside redecoration
- Walk the elevations once or twice a year
- Check that rainwater leaves the facade the way it was designed to
- Never let anyone seal over old sealant
Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.
Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and we clear our waste as we work. Work in places the size of Nash Mills is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
What we need from you
- Share the asbestos register for older buildings
- Send any specification or drawings in advance
- Move anything stored against the joints
