Doors by Cii Double Glazing in Essex

Doors

Make a statement from the moment you arrive home

Front, rear, and garden openings

We fit composite and uPVC entrance doors, stable doors for controlled ventilation, and French, sliding, bi-fold, and heritage aluminium doors for garden and extension openings. The right choice depends on what the opening has to do: security and kerb appeal at the front, practical everyday access at the rear, and light, views, and movement for garden rooms.

Measured before specified

French doors, aluminium sliders, and bi-folds each change the clear opening, threshold, hardware layout, and view through the glass. We measure first, then specify the frame material, opening style, locking, threshold, and glazing around the property before our own team installs it.

Door guide

Which door suits the house?

A good door choice starts with how it will look on the house: colour, glass, handles, letterplate, frame colour, and how the finish sits against the brickwork, render, windows, and roofline. Security and insulation should be specified properly on every door; the real decision is choosing the style that suits the property, then matching the opening type to how you use that entrance day to day.

Doors product comparison

Composite doors
Front-door colour, glass, hardware, and kerb appeal. Choose this when the front of the house needs a stronger style statement, a wider colour choice, and a more finished entrance look.
uPVC doors
Practical rear, side, and value-led access doors. Choose this when the brief is low maintenance, useful panel and glass choice, and a sensible replacement cost.
Stable doors
Ventilation, pets, children, garden access, and utility entrances. Choose this when the top half needs to open for air while the lower half stays closed for control.
French doors
Smaller hinged garden openings. Choose this when a simple hinged pair gives enough access without the track depth or panel stack of larger systems.
Aluminium bi-folds
Maximum clear opening to the garden. Choose this when opening up as much of the wall as possible matters more than the closed-door view.
Aluminium sliding patio doors
Large glass, wider views, and no swing space. Choose this when the view through larger glass panels matters more than opening the full wall.
Heritage aluminium doors
Slim steel-look divisions and period-style projects. Choose this when slimmer dark framing and divided glazing are part of the character of the property.

Door aftercare

The assurances behind your new door

Door choices often come down to security, threshold, weathering and daily use. These are the practical assurances behind the finished installation.

10YEARGUARANTEE

10-year guarantee

Covered beyond the day it is fitted

Door fitting is about alignment, locks, thresholds and weathering as much as the door slab itself. Our 10-year installation guarantee keeps the fitted detail accountable after handover.

Assure Certification

Assure certification

A recognised route for compliant replacement doors

FENSA is not the only recognised certification route. For qualifying external replacement doors, Assure gives us a Competent Person Scheme route for Building Regulations certification, with focused installer support if paperwork or technical questions need attention.

Checkatrade
Thoroughly recommend this company. From the first call I was given really helpful advice and fitters came out the next day. The fitter was very knowledgeable and helpful, completed the job, and gave good advice on other areas we needed looking at. Will definitely use again and have no hesitation recommending them to friends and family.

Good price and hassle free. The doors look brilliant, exactly what we wanted. The fitters were friendly and left everything spotless.
