Accurate dimensions
Installation that starts with the opening.
A door or window installation is about more than fitting a frame into an opening.
At D.J FIRST, we work from the dimensions and conditions of the property, taking care over measurement, positioning, sealing and finishing throughout the installation.
From individual residential windows and entrance doors to larger commercial glazing systems, our work is planned around the building and the requirements of each project.
What we install
Entry & Interior Doors
Carefully measured and installed doors for entrances, internal spaces and replacement projects.
Aluminium, uPVC & Timber Windows
Window installation matched to the property, opening and specification, with attention to alignment, sealing and finishing.
Larger Glazed Systems
Installation of glass curtain wall systems for contemporary residential and commercial buildings.
Three details that protect the finished installation.
01 — Air Tightness
Careful sealing around the installation helps reduce air leakage and unwanted draughts.
02 — Water Tightness
Weather sealing, flashing and properly finished joints help protect the opening from rain and moisture.
03 — Thermal Insulation
Appropriate installation methods and careful sealing help reduce unnecessary heat loss around doors and windows.
For homes and working spaces.
Residential
From replacing a single entrance door to installing windows throughout a home, we work with the requirements of individual properties and renovation projects.
Commercial
We also undertake installation work for commercial buildings where accurate measurement, coordination and careful finishing are essential.
What does installation cost?
Every installation is different. The final cost depends on the type and number of openings, measurements, existing conditions, access and the work required to complete the installation properly.

Installation
Once the work is confirmed, the installation is arranged and completed with attention to fit, sealing and finish.
The work is in the details.
Doors and windows are among the most visible parts of a building, but much of an installation’s quality is found around the edges — in the measurements, the positioning, the sealing and the finishing that are easy to overlook once the work is complete.
D.J FIRST focuses on getting those details right.
Our approach is straightforward: understand the property, measure carefully, install properly and leave the opening clean, secure and ready for use.
Whether it’s a residential replacement or a larger commercial glazing project, we treat the installation as part of the building rather than simply a product being fitted into it.
