Construction mastic for commercial buildings in Temple End
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. If you have inconsistent sealant finishes from plot to plot and internal caulk splitting as the building dries out, we can put it right, whatever the surface.

Sites and facades in and around Temple End
At about 31 miles from central London, Temple End is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Rainfall across the South East, Temple End included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.
Projects at schools like Hitchin Boys' School work to term dates, so mastic is programmed tightly. Hospital estates such as Pinehill Hospital (1.9 miles north-east of Temple End) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Further education sites such as North Hertfordshire College - Hitchin Campus (2.3 miles north-east of Temple End) are extended and refurbished from time to time, with mastic often programmed into the summer break.
Temple End is about 2 miles south-west of Hitchin, in Hertfordshire.

Questions about Temple End
Could you schedule work at a campus like North Hertfordshire College - Hitchin Campus for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you work on a hospital site such as Pinehill Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work to our specification?
We use the product the specification names. If we think an alternative would suit better, we put it to you first.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
What guarantee comes with a mastic package?
It’s backed by our 12-month guarantee on the workmanship. Protecting sealed areas from following trades helps avoid damage.
After the work
Regular inspection catches problems early. Specifically:
- Protect sealed areas from following trades
- Don’t force external sealing on a damp or frosty day
- Get the mastic subcontractor involved early in the programme
- Keep product details for future maintenance
Any damage after we have finished should go on the snag list right away. We can return to clear snags before handover, priced as part of the package or separately.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.

What else we do in Temple End
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Rework caused by others damaging completed areas
- Approving fire stopping as compliant
- Designing joint widths or choosing the specification (that sits with the designer)
Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod.

Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Different surfaces, different methods
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. A kitchen-suitable sealant is used, food-safe where food contact is possible.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
