New build and refits around Digswell
A 2-mile radius around Digswell takes in a number of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. Central London is about 23 miles from Digswell. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
Recladding or extending a unit at a site like Little Ridge Industrial Estate, 1.6 miles south-east of Digswell, brings panel joints and frame perimeters into the programme. Further education sites such as Oaklands College - Welwyn Garden City Campus, 1 mile to the south of Digswell, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Digswell is about 1 mile north of Welwyn Garden City, in Hertfordshire. We send applicators to Digswell for facade joints. Our Hertfordshire coverage takes in 371 places. Our London page has more on work in that area, about 23 miles away.

About our facade sealing in Digswell
A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear. If you have perimeter joints where frames meet the structure and hard, chalky sealant that no longer flexes, we can put it right, on coping and flashing joints, window and door perimeters and shopfront frames alike. Whoever orders the work in Digswell, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
On a small site around Digswell, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

How the quote is worked out
We price every job individually. The main factors are:
- Access and working height
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- Distance, for remote addresses
A quote for facade joints depends on quantities, condition and access. Ask us for a fixed quote.
Details that help us quote
To price the job accurately, we need a clear picture of the site. Send us:
- When you need the work done
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
- How the joints are reached, and at what height
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Do you need facade sealing in Digswell?
Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.
Common reasons buildings call us in:
- Sealant pulling away from frames or panels
- Cladding panel joints that have opened up
- Weathered joints at frame-to-structure perimeters
- Cold air coming in at window perimeters
Work at a hotel such as The Wellington Inn Hotel (to the north-west of Digswell) tends to be programmed around bookings, mastic included.
What to look for in a quote
- How joint depth will be controlled
- How long is the guarantee, and what does it include?
- Their pre-qualification and accreditations
- How the joint faces will be prepared and primed
On site: what to expect
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. If neighbouring businesses or buildings around Digswell need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
What we need from you
- Warn occupants and staff about the work
- Flag any permit to work we will need
- Point out parking and an unloading spot

Questions about Digswell
Is a smaller place like Digswell outside your area?
Not at all. Digswell is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Is hospital work, at somewhere like Queen Elizabeth II Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
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.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
Which sealant do you use on facades?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, depending on the substrate and the specification.
When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Damaged frames that need replacing
- Joints too narrow for the movement they take, which need redesign
- Providing access systems for the work
Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly before you book.

Different surfaces, different methods
Brick and stone facades
Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in finished to throw water off the joint.
