WINDOWS, DOORS, CONSERVATORIES, REPAIRS & MORE!

The double glazing industry has a bad name for pushy sales and confusing prices, but our ‘straight-up’ pricing is highly competitive without hidden or inflated costs. If you’d like us to come and see you then one of our experienced team, will run through what you need and suggest the best windows, door or conservatory based on what’s right for you and your home.

We also provide smart roof replacements, so if you find your existing conservatory is too hot in the summer or too cold in the winter, then we can create an all year round usable space with a Thermally controlled smart roof. These often change how people use their homes and customers find they have an extra room for entertaining or relaxing. They can also potentially increase the value of your home.

With nearly 20 years of experience 3SG have worked with too many local clients to list, providing new windows, doors and conservatories throughout Olney, Buckinghamshire and Nationwide. The company has an unrivalled reputation in the window industry for reliability, honesty and getting the job done to a high standard.

  • “3SG has done high quality work for us over the past ten years, they have always been very trustworthy, competent & competitive.

    In their work, no job was to small or large for them. I would not hesitate to recommend them to anyone else.”

    Mark Hone, Bedford Hospital NHS Trust
  • “Thank you so much to Three Shires for our beautiful back door and our number glazed above our front door. They took great care to ensure we chose the best door for our needs, showing us loads of ideas and images of previous work. We left them to choose how the number above the front door would look and it’s perfectly in keeping with the property. All in all excellent and very professional service from the moment we contacted them for a quote to the installation and after care. Will definitely use them again.”

    Philippa Graham
  • “We used 3SG to upgrade the old conservatory roof / windows after moving into our new house this year. We have an open plan kitchen / conservatory which was unable to be used as was just too hot in the summer due to the plastic roof. 3SG offered a competitive quote for replacing the roof with a warm roof as well replacing the doors/windows to meet building standards.

    The team were extremely friendly, professional and worked hard to ensure work was completed within the agreed timeframe. We are very happy and can actually use the space now as it was intended. I would highly recommend 3SG.”
