What types of doors do you offer?

We supply and install uPVC and composite doors including residential front doors, French doors, sliding patio doors and bi-folding doors. Each style can be specified with different glazing options, thresholds and finishes to suit traditional and modern Sussex homes.

Do you supply doors only or do you install too?

Both. We can supply doors to trade or DIY customers, or carry out a full supply-and-fit service with FENSA certification and our 10-year insurance-backed guarantee.

How energy efficient are your doors?

We use Planitherm glass, Argon-filled sealed units, thermal warm-edge spacers and multi-chamber frames to deliver improved U-values and reduced heat loss. Proper installation and airtight sealing are equally important — our FENSA-qualified fitters ensure the correct installation to maximise performance.

How long will the installation take?

Times vary by specification and property access, but after the survey we confirm a clear installation date. Our team works efficiently to complete standard door replacements in a day while larger projects such as bi-folds may take longer — we'll confirm timescales when we quote.

What guarantee and certification do you provide?

Every installation is completed by FENSA MTC-qualified installers and issued with FENSA certification. We also include a 10-year insurance-backed guarantee on installations for added protection.

About This Service

uPVC Doors

The Window Workshop supplies and installs uPVC and composite doors for homes across Peacehaven and East Sussex. From classic residential and French doors to bi-folding, patio and sliding options, every door is specified with Planitherm glass, Argon-filled units and multi-chamber frames for genuine thermal performance. Installers hold FENSA MTC qualifications and every job receives FENSA certification plus a 10-year insurance-backed guarantee. Expect tidy, respectful fitters — experienced local tradespeople who leave your home clean and secure.

Our Process

How It Works

Site survey & specification

A local installer visits your home to measure, check thresholds and discuss finishes, glazing and security so your door is specified to suit the property — Victorian terrace, 1930s semi or coastal bungalow.

Sourcing & quality checks

Doors are sourced from trusted suppliers using Planitherm glass, Argon gas units, thermal warm-edge spacers and multi-chamber frames, specified to your exact requirements and checked before delivery to ensure fit and finish.

Professional installation & handover

Our FENSA-qualified team fits the door with care, completes airtight sealing and finishings, issues FENSA certification and explains maintenance — leaving your home clean and secure.

Bespoke doors for Sussex homes. Whether you want a traditional residential front door for a Peacehaven terrace, wide French doors for a Sussex kitchen extension, or smooth-sliding patio and bi-folding doors for a coastal bungalow, we source and supply to order. Components are selected for performance: Planitherm low-emissivity glass, Argon-filled sealed units, warm-edge spacers and multi-chamber uPVC frames that cut cold bridging and reduce condensation. Finish options range from classic white and woodgrain foils to matt colours so your new door complements brickwork, weatherboarding or render.

Supply, fit or trade supply. Family-run since 1998, The Window Workshop offers supply-only orders for builders and DIYers as well as full supply-and-fit packages. Our FENSA-qualified fitters — including Mark, Steve and James — focus on tidy, courteous installations and secure handovers.
