Concrete Garage Specification

Dencroft concrete garages are manufactured to a high standard using durable materials, proven construction methods and practical design features. Every garage is built with strength, weather resistance and long-term use in mind.

Whether you are choosing a single concrete garage, double garage, prefab garage or larger sectional building, our team can talk you through the specification and help you choose the right options for your property.

Concrete Garage Walls

The walls are one of the most important parts of any concrete garage. Dencroft garages are built using our advanced tongued and grooved interlocking concrete panels, designed to provide strength, rigidity and a neat external finish.

The panels are machine vibrated and reinforced with high-yield steel, helping to create a strong sectional garage structure. A standard garage is supplied with Canterbury Spar finish, while other finishes may be available depending on the chosen design.

Popular finishes include options such as Derbyshire Spar, Yellow Spar, White Spar and other decorative finishes, allowing your concrete garage to suit both practical needs and the appearance of your property.

Unique Base Unit

On many Dencroft models, the concrete panels are positioned on a steel-reinforced concrete foundation unit. This base unit is designed to provide extra strength and support at ground level.

The unit helps reduce the need for fully built-up fascias and can enable better alignment, flexibility and installation accuracy when the garage is erected on site.

Roofing and Weather Protection

The roof is manufactured using heavy-duty corrugated cement fibre roof sheets. These sheets are non-combustible, low maintenance and resistant to rust, making them a practical choice for prefab concrete garages and sectional buildings.

The roof sheets are also partially breathable, which helps reduce the internal build-up of moisture and supports better ventilation inside the garage.

Each roof sheet is securely fixed to specially engineered steel angle trusses. The trusses are treated with bitumen paint for long-term protection, while concrete gables are supplied with eaves fillers as standard to help guard against extreme weather.

Garage Doors

All Dencroft garages are supplied as standard with a white powder-coated up-and-over garage door, available in a choice of styles including Vertical Ribs, Horizontal Ribs, Georgian and Wood Effect.

Depending on your requirements, other garage door options may also be available. Our team can help you choose a door style that suits your garage size, access and overall appearance.

Windows, Fascias and Finishing Details

A Dencroft concrete garage can be tailored with practical finishing details such as windows, side doors, fascias and external trims. These options help make the building more useful, more attractive and better suited to the way you plan to use it.

All timber used is treated with a protective wood preservative. Fixings are galvanised or zinc plated, while roofing bolts include plastic sealing washers for additional protection.

Built for Strength and Everyday Use

Our concrete garages are designed to offer a dependable, low-maintenance solution for homeowners who need secure storage, vehicle protection, workshop space or a practical outbuilding.

From the interlocking wall panels and reinforced base system to the roof structure, doors and finishing details, each part of the specification is chosen to support a strong and reliable garage.

Choose the Right Garage Specification

Every property is different, so the right garage specification will depend on the size of your plot, access, vehicle requirements, storage needs and preferred appearance.

Dencroft Garages can advise on garage sizes, roof styles, panel finishes, doors, windows and optional extras, helping you choose a concrete garage that works for your home and budget.

 Trustindex verifies that the original source of the review is Google. For a number of years, the leaks and condensation in my garage had been getting progressively worse, to the extent that I was having to sheet my car and cover shelves and a workbench to keep them dry.
The time had come for a re-roof to cure the problem.
I compared various companies and received estimates for the work.
I chose Dencroft, not just on price alone, but for the efficient way they handled my enquiry.
Telephone calls were answered promptly by Christine in the office, whose friendly nature, knowlegeable and positive approach, inspired confidence in the company.
An estimate was given over the phone, followed by  a site survey to confirm the price.
A paper copy was then received by post the next day and the job was booked.
A little later, I received telephone confirmation of the date for the new roof to be fitted.
Rob and Denis, then arrived on the day to remove the old leaking roof panels and replace them with new metal sheets.
Very polite and obliging, they got on without any fuss adapting the job to suit my needs and requirements.
All waste was removed from the site, which was left spotlessly clean.
In all, I am completely satisfied with the whole process and can recommend Dencroft with full confidence.

Many thanks to Christine for her pleasant telephone manner and efficient customer service, Rob and Denis for their practical skills, adaptability and friendly nature on site.
You are all a credit to the company and deserve due recognition as such.
From a very satisfied customer.

 Trustindex verifies that the original source of the review is Google. We had our very old garage dismantled and a new shed erected in its place. It was all very hassle free right from our first visit to the site to completion. One of the windows hadn't been delivered for the arranged date, but they came and did the major work anyway and we're back within a week to complete. I identified a couple of snagging issues which they also rectified, without question, on the return visit. Everyone we dealt with was courteous and helpful, and the lads who came out were friendly, worked  efficiently and knew what they were doing. An excellent service all round, and value for money.

 Trustindex verifies that the original source of the review is Google. What an absolute pleasure to deal with this highly professional company. We had our garage roof replaced 5 years ago by Dencroft Garages, and it has been great! However, during the wild weather recently, some of the fascia had popped off. I contacted Dencroft Garages by email and received a reply straight away from Christine. Glen came over today to fix it up, within a couple of weeks of me raising the issue. Really friendly, really professional and most of all, he did an excellent job. I cannot recommend this company highly enough! Thankyou!
