Door Installation & Replacement

Doors are an important part of a property’s performance, security and overall finish. Internally, they provide privacy, acoustic separation, and a consistent finish. Externally, they affect thermal efficiency, weather resistance, access and first impressions.

At DS5 Construction Ltd, we install internal and external doors for residential and commercial projects across London. Our service includes standard door sets, glazed doors, sliding systems, bifold doors, fire doors and bespoke doors. Every installation is carried out with close attention to alignment, ironmongery, frame integration and smooth day-to-day operation.

Door Options

Aluminium Doors
are ideal for summer houses and extensions. They offer slim sightlines, strong structural performance, a refined appearance and excellent durability. Their strength and clean detailing make them particularly well suited to sliding and bifold systems with larger glazed panels.
uPVC Doors
uPVC doors are a practical and cost-effective choice for front, rear, patio and French door applications. They offer good thermal efficiency, low maintenance and reliable everyday performance. Available in a range of solid and glazed designs, they suit a wide variety of residential properties.

What the service includes

Our door installation service includes removal of existing frames, installation of new linings or frames, door hanging and adjustment, and fitting of handles, locks, hinges and closers. We also carry out threshold detailing and fire door installation where required. On larger projects, door installations are coordinated with flooring, wall finishes, glazing and access requirements.

How we deliver it

Even a high-quality door will underperform if it is poorly installed. Correct clearances, proper hinge setting and accurate frame alignment are essential. Fire doors, glazed doors and external systems require additional care to ensure compliance, effective sealing and reliable long-term performance. We treat doors as precision elements, not simply finishing items.

The result

A properly fitted door should operate smoothly, close cleanly and sit consistently within the surrounding finishes, contributing to the overall quality, comfort and appearance of the property.
