Contractors’ notes for Highfield
Central London is about 24 miles from Highfield. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. Hemel Hempstead, one of the planned towns of the twentieth century, takes in or adjoins Highfield. Regeneration of planned-town buildings brings recladding and replacement windows, each with joints to seal.
For contractors at a school such as Yewtree Primary School, sealing has to be finished before term starts. For a contractor working at a hospital such as Hemel Hempstead Hospital, 1.1 miles to the south-west of Highfield, perimeter and facade sealing is planned around patients and deliveries. Units on estates such as Bellgate shopping centre, less than half a mile to the west of Highfield, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

About our facade sealing in Highfield
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. Most enquiries involve previous reseals run over old sealant and discoloured or dirty facade joints, on shopfront frames, window and door perimeters and stone and brick facade joints. For commercial sealant work in Highfield, you deal with one contact from quote to sign-off, whether it’s one building or several.
Building work in places the size of Highfield is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Your questions answered
Do you take on work at healthcare sites like Hemel Hempstead Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Could you schedule work at a campus like West Herts College for the vacation?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Can you find out why a window is leaking?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we will tell you which.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What happens if it’s left?
Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. For buildings in places like Highfield, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What else we do in Highfield
Maintenance after handover
A few simple habits keep the new joints working:
- Investigate damp beside windows promptly
- Combine resealing with other works that need access
- Never let anyone seal over old sealant
- Check that rainwater leaves the facade the way it was designed to
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.
Surface by surface
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed using a sealant classified for that use.
Window and door perimeters
Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus neutral-cure product, chosen for the frame and wall, goes in finished to throw water off the joint.
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Joints too narrow for the movement they take, which need redesign
- Water getting in through cracked render or porous masonry
- Specialist high-level access methods
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think.
