Double Glazing
About This Service

Double Glazing

The Window Workshop has supplied and installed double glazing across Sussex since 1998. We work with trusted suppliers to source Planitherm glass, Argon-filled units, warm-edge spacers and multi-chamber frames for genuine thermal performance. FENSA MTC-qualified installers issue certification with every job and our 10-year insurance-backed guarantee gives long-term peace of mind. We also carry out repairs and maintenance to extend the life of existing windows and doors.

Our Process

How It Works

01

Survey & Measure

A local surveyor visits your property in Peacehaven to confirm sizes, reveal vents, check sills and discuss styles, energy targets and planning requirements before we quote.

02

Sourcing & quality checks

Sealed units and uPVC or aluminium frames are sourced to order from trusted suppliers — the right colours, glass specification and build quality for your property.

03

Fit, Test & Certify

Our FENSA MTC-qualified fitters carry out a tidy installation, test seals and drainage, leave the site clean and issue FENSA certification plus the 10-year insurance-backed guarantee.

Sourced and fitted across Sussex. The Window Workshop supplies double-glazed sealed units and frames to order, with accurate custom sizes for bay windows, vertical sliders and heritage-style frames, plus a wide choice of foils and hardware. We specify Planitherm low-emissivity glass, Argon-filled cavities and warm-edge spacers as standard where required, and can supply either uPVC or aluminium systems depending on the project.

Repairs, upgrades and aftercare.If a sealed unit has failed, or your frames need adjustments, we provide unit replacement, draught sealing, hinge and handle renewals and periodic maintenance to prolong performance. Every installation is completed by FENSA MTC-qualified fitters and issued with a FENSA certificate and our 10-year insurance-backed guarantee. For trade or DIY customers we also supply units and components direct.

“I had a great experience with the window workshop from initial contact to job completion. Dan was very responsive with my window query and came over to assess/quote for the job very quickly which I appreciated. Steve replaced our window and he did an incredible job, it’s really transformed our bathroom already. He also demonstrated a high level of professionalism as well as being very friendly. I appreciated him being as quiet as he could completing the job and he tidied up to a high standard. Thanks again window workshop. I’m sure we will be in touch again for a new front door!”

Daniel first came around to give us a quote and was polite, friendly and professional with a wealth of knowledge which automatically put us at ease. We had both our new front door and conservatory fitted and installed and are very pleased with the results (pictures added below) Mark, Steve, Paul, Dean and James were all very professional, polite and hardworking. We'll definitely be using their services again when the need arises.”

“Daniel at the window workshop is absolutely brilliant. It was a relief to speak with him after experiencing the aggressive sales tactics of the big national window companies. We’re delighted with our new windows and the whole team were a delight to have in our home doing the fitting. Polite, tidy and good fun too! If we need more windows in the future we will go straight back!”
