About our facade sealing in Hudnall
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. We work on stone and brick facade joints, window and door perimeters and cladding panel joints, and the failures we’re asked to look at most are old perimeter mastic that has dried out and unsightly perimeter sealant on a visible elevation. One point of contact handles commercial sealant work in Hudnall from the first photos to the final walk-round, for single jobs and planned programmes alike.
Conversions of older rural buildings near smaller places such as Hudnall bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Our process
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Hudnall are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Getting the site ready
- Confirm the product named in the specification
- Arrange parking or a loading space
- Share your working hours and any access restrictions

Advice
Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Owners, agents and contractors
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Other services in Hudnall
Hudnall: questions and answers
Is a hospital such as Hemel Hempstead Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Hudnall too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
How do we ask for a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you install glazing systems?
No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters.
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Will you check whether the sealant is causing the leak?
Yes. We check the sealant joints and report what we find before quoting. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Mastic packages on Hudnall sites
Central London is about 29 miles from Hudnall. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.
For a contractor at a hotel such as The Bridgewater Arms Hotel (0.8 miles north-west of Hudnall), the mastic often has to be finished before a reopening date.
Hudnall is about 3 miles north of Berkhamsted, in Hertfordshire. We cover Hudnall and the rest of Hertfordshire, with the same fixed quotes and 12-month guarantee as everywhere else. 371 places across Hertfordshire fall within our area, Hudnall among them.

After the work
Once the work is signed off, these steps help:
- Plan facade sealing alongside redecoration
- Keep pressure washers away from fresh sealant
- Avoid patch repairs on failed facade joints
- Keep sills, gutters and drainage paths clear
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down.
Do you need facade sealing in Hudnall?
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.
Any of the following is a good reason to get the joints checked over:
- Perimeter joints where frames meet the structure
- Discoloured or dirty facade joints
- Gaps between rainscreen or cladding panels
- Weathered facade joints that have lost their grip
Extensions at sites like Hemel Hempstead Hospital, 5.1 miles to the south-east of Hudnall, usually sit beside working departments, and the mastic follows strict access rules.
What to look for in a quote
- Their pre-qualification and accreditations
- The terms of the workmanship guarantee
- Whether primer will be used where the manufacturer specifies it
- Is the sealant right for the movement and the substrate?
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Cracked or spalling substrates that need repair before sealing
- Specialist high-level access methods
- Water getting in through cracked render or porous masonry
If you’re not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
