Expert Masonry & Blockwork in Hertfordshire – Built to Last by ShellCo
Every Course Straight. Every Wall Sound.
At Shellco, we build walls that hold weight — and hold attention. From structural blockwork to decorative brick and stone, every course we lay is straight, clean, and built to spec.
We handle full shells, retaining walls, cavity construction and more — all with the accuracy, speed and pride of a team that knows how to get it right the first time.
Whether we’re part of the main contract or brought in for just the masonry, you’ll get the same thing: solid structure, sharp finishes, and work that lasts.
Our Proven Build Method
-
Step 1: Site Assessment & Marking Out
We confirm all levels, wall lines, and structural alignment before the first block is laid. -
Step 2: Base Courses & Setting Out
The foundation courses are laid with stringlines and levels, ensuring every wall runs straight and true. -
Step 3: Damp-Proofing & Build Prep
DPCs are installed, insulation zones prepped, and all cavity requirements double-checked before lifting begins. -
Step 4: Lifting & Finishing
We build to spec, lift by lift, with bond pattern, insulation cavities, DPCs, and expansion joints where required.
