What our accreditations mean for you
When you choose an installer, the details behind the badges matter. Here’s what our registration, membership and guarantee mean.
CERTASS registered
CERTASS operates a government-authorised Competent Person Scheme for qualifying replacement windows and doors. Registered installers are assessed and audited. Eligible work can be certified for Building Regulations compliance, with notification to the local authority and a certificate for the homeowner. Keep the certificate with your property documents.
Federation of Master Builders
The Federation of Master Builders (FMB) is a trade association for building companies. Members are vetted and their work inspected as part of its membership standards. Spectrum’s membership gives you an additional check when choosing a company for your home improvement project.
Insurance-backed reassurance
We offer a 10-year insurance-backed guarantee on qualifying installations. This provides protection under the policy terms if the installing business ceases trading and cannot honour covered guarantee obligations. Your quotation and policy documents confirm eligibility, exclusions and the cover for your installation.
Replacement Windows in Essex
Replacing your windows starts with how you want your home to look and feel. Spectrum Glazing installs replacement windows across Colchester, Brightlingsea and Essex, helping you compare uPVC and aluminium frames, opening styles and glazing choices. Choose familiar casement windows, a flush finish for clean lines, timber-look designs for traditional character, or sliding sash windows to complement a period property. We can discuss colours, handles, ventilation and the specification suited to each room. If you are comparing double glazing in Essex, bring your priorities and existing window details to the showroom. A survey then confirms measurements, installation requirements and the options included in your quotation.
Find Your New Front Door
Your entrance sets the tone for your home. Explore composite doors for a wide choice of designs, premium aluminium entrance doors for a contemporary finish, or practical uPVC front and back doors. Compare colours, glazing, handles and the complete security specification with our team. We will help you choose a door that suits your property and the way you use it.
New Conservatories
Create an additional room with a new conservatory designed for your property. From a practical lean-to to a traditional Victorian or a bright gable-fronted design, start with the space you need for dining, relaxing or family time. We can discuss the layout, frames, glazing and roof together, with the survey and required permissions considered before installation.
Already have a conservatory? Explore replacement roof options separately.
Conservatory roof replacement →hup! Home Extensions
Make room for a kitchen-diner, a dedicated home office or open-plan family living. The hup! system offers a route to a home extension that can be tailored to the way you want to use your space. Discuss the layout, glazing, roof and external finish with Spectrum, and explore genuine local projects to see different approaches. The survey confirms what is suitable for your property.
