Common questions from Digswell clients
Will you take on work at estates like Little Ridge Industrial Estate, close to Digswell?
Yes. Estates, retail parks and business parks around Digswell, Little Ridge Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is Digswell too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
What do you charge?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact.
Will you stick to the specified products?
The specification decides the product. Product standards such as BS EN 15651 are often named in specifications.
Construction mastic in Digswell
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place, and one applicator team gives a consistent finish. The enquiries we see most involve failed sealant in an existing building being refurbished and frame perimeters left unsealed or poorly sealed, on window and door perimeters, brick and block movement joints and sanitary and kitchen joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Digswell, that means joint design, primers and backing rod as standard.
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.
Every job we finish is backed by a 12-month workmanship guarantee, in Digswell as everywhere else we work. If our installation lets you down in that time, we return and fix it.

After the work
To get the most from the new sealant:
- Keep scrapers and abrasive pads off new beads
- Don’t schedule sealing before decorators and flooring are done
- Keep finished joints away from paint, plaster and scrapers
- Plan external elevations with the weather in mind
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault which is why protection after sealing matters.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks so external sequencing builds in some flexibility.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and our waste is bagged and taken away as we go. 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.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Flag any permit to work we will need
- Warn occupants and staff about the work

For managing agents and facilities managers
Building owners and managing agents use us on everything from one building to a spread of sites around Digswell. One quote can cover more than one site, which keeps the paperwork simple.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- How much there is to seal
- The product specified
- Working within restricted access windows
- Any access equipment needed
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What to include in your enquiry
However big the job, the same details help:
- The site address and postcode
- How the joints are reached, and at what height
- When you need the work done
- Approximate linear metres or a joint schedule
Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, ring 01277 525 020 or use the quote form.
Do you need construction mastic in Digswell?
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond.
Clients usually get in touch after noticing one or more of the following:
- External joints sealed in damp or cold conditions that are now failing
- A mastic package split between trades with no clear owner
- Caulk cracking where joints are moving more than expected
- Sanitary sealant damaged by following trades
New wings at hospitals like Queen Elizabeth II Hospital, 2.5 miles south of Digswell, bring long runs of window and panel joints to seal.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Whether old or failed sealant will be cut out, not overlaid
- How joint depth will be controlled
- Proof of insurance
Facades, frames and programmes in Digswell
The area within 2 miles of Digswell holds several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Digswell is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.
Further education sites such as Oaklands College - Welwyn Garden City Campus (1 mile south of Digswell) are extended and refurbished from time to time, with mastic often programmed into the summer break. For contractors on a campus like University of Hertfordshire, 4 miles south of Digswell, facade and perimeter sealing has to fit around students and term dates.

Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
