Window Installation
We provide expert installation of energy-efficient windows, including casement, flush casement, and vertical sliding designs. Our UPVC and aluminium options enhance thermal insulation, reduce noise pollution, and improve property security. Tailored to residential and commercial properties across Essex, our installations are REHAU-certified and backed by comprehensive guarantees.
Conservatory Building
Our bespoke conservatories combine functionality with aesthetic appeal, available in Edwardian, lean-to, and P-shaped designs. Constructed with high-quality UPVC or aluminium frames and insulated roofs, they create year-round living spaces that increase property value while meeting strict energy efficiency standards for Colchester homeowners.
Door Replacement
We supply and install composite, bi-fold, and French doors engineered for security and thermal performance. Our products feature multi-point locking systems and weatherproof seals, available in custom colours and finishes to complement property styles ranging from period homes to modern developments in Ipswich and surrounding areas.
Secondary Glazing
This cost-effective solution improves insulation by adding an extra pane to existing windows. Ideal for listed buildings in conservation areas, it reduces heat loss by up to 10% and external noise by 50%, with discreet, removable units that preserve original window aesthetics while enhancing energy efficiency.
Commercial Glazing
We deliver tailored glazing solutions for retail, office, and industrial properties, including aluminium storefronts and security-rated doors. Our commercial team provides free surveys, project management, and compliance with building regulations, ensuring minimal disruption for businesses across Chelmsford and the wider Essex region.
Questions
How does double glazing improve energy efficiency?
Double glazing traps insulating air between panes, reducing heat loss by up to 20% and lowering annual heating costs through improved thermal retention.
What window frame materials are available?
We offer UPVC, aluminium, and wooden frames, each offering distinct benefits in insulation, maintenance, and aesthetic appeal for residential and commercial properties.
Do conservatories require planning permission?
Most conservatories qualify as permitted developments, though listed buildings and conservation areas may require additional approvals from local authorities.
How long does window installation take?
Replacing four standard windows typically takes one day, with larger projects like full-house installations completed within a week, depending on complexity.
Are composite doors secure?
Composite doors feature reinforced cores and multi-point locking systems, making them highly resistant to forced entry while maintaining aesthetic appeal.
Can secondary glazing reduce noise?
Yes, secondary glazing can reduce external noise pollution by up to 50%, making it ideal for properties near busy roads or urban environments.

Had a side door removed and replaced and we were really happy with the service and quality of door. Fitting was quick and straight forward and we are happy with the finish. Reasonably priced and would use again. We opted for a composite door in green and so far are very happy with it.

Report
Poor company. I held back 500 of a 5k job because i wasn't happy with a few bits with the full intention of paying when problems were rectified. They turned up telling me to pay the money now or they would take the front door off. A year later when i was getting some work done which exposed the ceiling, it revealed they had sawn through a joist when fitting the front door...we invited them out to show them. They turned up but never heard from them again. Don't fall for the charms of the salesman. Never heard from him again once problems occured. The owner said, 'how was he supposed to know
