Expert Mechanical and Gas Services
Mechanical Infrastructure Specialists
Our Engineers provides expert boiler and pipework installation for both domestic and commercial properties. Our engineers craft tailored systems that account for your current demand and future scale. We prioritise high-efficiency outcomes and robust layouts to ensure your facility maintains peak operational performance with maximum reliability and minimal maintenance interruption.
Gas Safety Testing and Commissioning
Our team is able to conduct strength testing and purging for all types of gas infrastructure. By utilising precision-calibrated tooling, we verify the absolute integrity of your pipework before any gas is introduced. We manage the entire safety protocol from start to finish, ensuring your site remains fully compliant with the latest industry regulations and security standards.
Chain Trenching
Day Gas and Mechanical Services provides chain trenching for fast, accurate installation of underground services. Using specialist trenching equipment, we can cut clean, consistent trenches for gas, water, power and communications. This method reduces manual digging, speeds up installation and leaves a neat, narrow trench that is easier to backfill and reinstate, helping keep projects on time and on budget.
Moling and Trenchless Technology
We are able to use moling and other trenchless techniques to install new services with minimal surface disruption. Ideal for roads, driveways and landscaped areas, our trenchless methods reduce excavation, traffic management and reinstatement costs. We plan each mole launch carefully to avoid existing utilities, providing a cleaner, faster and less intrusive way to upgrade your underground networks.
Flowstopping
We are able to offer professional flowstopping solutions to safely isolate sections of live gas and water mains. We use approved techniques and equipment to create temporary blocks, allowing repairs, alterations or tie-ins to be completed without draining or shutting down the full system. This controlled approach reduces risk, saves time and keeps critical services available for your customers.
Replacement Gas and Water Mains
Our Team undertakes replacement of ageing or damaged gas and water mains, from planning through to reinstatement. Our team selects suitable materials and methods for each site, managing excavation, installation, testing and commissioning. By upgrading your network with minimal disruption, we help improve reliability, reduce leakage and extend the life of your infrastructure.
Hot Tapping and Under Pressure Drilling
We offer advanced under-pressure drilling solutions that allow for new service connections without requiring a total system shutdown. This specialised hot tapping technique prevents operational downtime and maintains service continuity for gas and water networks. Our technicians work across various pipe materials and sizes to deliver precise, permanent connections while your system stays fully functional.
Welding and Fabrication
Day Gas and Mechanical Services also offers a full range of welding solutions, including ARC, MIG and TIG welding. Our skilled welders can handle repairs, modifications and new fabrications in steel and other metals. With our own in-house fabrication facilities, we can design, build and finish bespoke pipework, brackets and frames to suit your project, keeping quality high and turnaround times short.
Over Head Heaters
We provide a full installation service for overhead heaters, from initial site survey and design through to safe, compliant fitting and commissioning. Our engineers assess your space, plan the best heater layout, and install all pipework, supports and controls to current regulations. This ensures your system runs efficiently, delivers even heat coverage, and integrates smoothly with your existing mechanical and gas infrastructure.
Gas Boosters
Our Engineers can supply and install gas boosters to maintain the correct pressure for critical appliances and plant. We assess your system demand, select suitable booster units and integrate them with your existing pipework and controls. With proper design, installation and commissioning, our gas booster solutions help ensure stable pressure, efficient combustion and reliable operation of your equipment.
