Your choice of double glazed window designs

Let natural light in and keep the elements out with energy-efficient double-glazed windows. Choose from a range of windows that offer noise reduction, enhanced security and stylish aesthetics to suit your home.

Casement Windows

Casement windows are hinged on one side and open outwards with a handle. They provide excellent ventilation and airflow and offer a tight seal when closed for energy efficiency. They are popular for their functionality and aesthetics, ideal for both residential and commercial spaces.

Bay Windows

Bay windows are architectural features that project outward from the main walls of a building. They typically consist of three or more windows arranged at angles, creating a bay or alcove. Bay windows enhance interior space, offer panoramic views, and allow ample natural light to enter the room.

Aluminium Windows

Aluminium is a lightweight and durable metal, making aluminium windows a popular choice for both residential and commercial buildings. The slim profile of aluminium windows also makes them a good option for contemporary architectural styles

uPVC Windows

uPVC windows, short for unplasticised polyvinyl chloride, are made of a durable and low-maintenance material. They offer excellent insulation properties, soundproofing, and weather resistance. They are popular for their energy efficiency and affordability.


Sash Windows

These traditional window designs consist of one or more movable panels, or sashes, that slide vertically or horizontally within the window frame. They often feature a counterbalance mechanism for smooth operation and are suited to older properties for a classic, timeless look.


Hardwood Sash Windows

Hardwood sash windows offer timeless elegance, exceptional durability, and natural insulation. They have a classic design and sturdy construction to ensure longevity. With proper maintenance, they withstand the elements and provide superior energy efficiency, making them a sustainable and stylish choice for any home.

First class service

I've just had roof insulation installed by The Home Improvement Project Ltd people and I can honestly say that it is brilliant!

The company itself is EXCELLENT. They treat you like a human being, and not just a number, and provide a FIRST CLASS service. The lads that came to do the work were polite, friendly, efficient and fast. I have used this company before regarding Wall Coatings and the service was equally as good now as it was then.

On time and respectful

A very professional company right from the rep to the office staff - but particularly the men who did my resin footpath and patio area. They were on time every morning, clean, tidy and respectful of the surrounding garden. I would certainly recommend this company.

Amanda C, Milton Keynes

Fantastic company

Fantastic company, and thoroughly professional throughout. Extremely happy with the end result, had our wall painted and drive done. So efficient, cleaned up everything , friendly and the guys who did the jobs were great, really reliable and extremely punctual. Excellent after care service. I have and will always recommend The Home Improvement Project Ltd. Thank you once again.

Victoria T, Kettering

Loved the final result

Overall we are very satisfied with the final result. We went from a polycarbonate roof to a solid roof with skylights. In the hot weather the polycarbonate roof was unbearable inside. The solid roof allows us to use the room during hot weather, plus we have the added benefit of extra light from the full length skylights.

The fitters were fine, professional, courteous and tidy, each making sure they did as good a job as possible.

Matthew I, Cambridge

More than satisfied

John B, Cambridge

Very much to our satisfaction

The work was carried out exactly as contracted and very much to our satisfaction, in an efficient, friendly and professional manner.

We are more than happy with the results and would be pleased to recommend THIP company to any prospective client.

Jess H, Cambridge

Excellent job

A two person crew turned up on time, work commenced almost immediately. Dust sheets were laid and work was continuous until completed.

I was notified as work progressed so that it was possible to see the process and Leo discussed any concerns that I may have had. No problems, excellent job!

Lloyd L, Brampton

Very professional from start to finish

The work proceeded on time, and the workmen were very helpful, polite and explained the process… Throughout, the workmen proceeded in a very professional manner keeping the disturbance to us to an absolute minimum.

We would not hesitate to recommend this company in future and we are very pleased with the result of the work carried out. The Home Improvement Project company.

Kathy C, Hitchin

The Home Improvement Project company.

Quality of work, courtesy and communication

We’ve just had an excellent new coating applied to our walls and I can thoroughly recommend The Home Improvement Project for the quality of work, the courtesy, communication and care taken by the installers and the friendliness, professionalism and efficiency we’ve encountered from everyone in the company with whom we have had contact. Well done and thank you very much indeed.

Della G, Northampton

My drive looks amazing!

I have just had a resin drive completed and I am so happy with the work, my drive looks amazing. Thank you to all the men who came and laid the resin drive for me, they worked very hard and were polite at all times. I am so pleased with this company that I have asked them to complete some more work on my house. Highly recommend this company.

Iron Staining Disclaimer: Rust staining or Iron staining is a natural problem that can occur when specific individual stones within the product that have high iron content are exposed to the environment. This problem is often increased if the site is in an exposed or coastal region. It is not unusual for the problem to take a number of years to be exposed and there is no way of identifying if the aggregate is affected prior to application.

It is not possible to screen the iron content out of the product by using magnets as it is part of the chemical makeup of the aggregate. The aggregates affected by this problem are mostly flint or gravel based type products or aggregates that have usually been quarried from glacial or river deposits. Using Calcined flint aggregates will not eliminate this problem if the raw flint used already has high iron content.

Given that iron staining is a natural occurrence no guarantee can be given or liability accepted for areas affected by iron staining. Since 2016 The Home Improvement Project have only selected aggregates from quarries that have proven records of low iron content. Whilst iron staining can cosmetically spoil the appearance of the affected areas it has no detrimental effect on the render itself.
