Doors & Windows

We have a great reputation for quality relacement doors and windows all fitted by our team of qualified and experienced tradesmen.

We install Rock doors which we believe are the very best in UPVC doors. The security is second to none with steel reinforcing to create a safe home.

All our windows come with full steel re-enforcement, multi-point locks and key locking handles. The glass units in our frames are 28mm argon filled.

Doors and windows are available in many designs with smooth or grained finish, beautiful handles, locks, and in any colour you desire.



Redwood Construction prides itself on being an extension and loft conversion specialist. We have been producing first class work in this area for over 25 years. Our work ranges from small kitchen extensions to a double storey wrap around incorporating the loft.

We pride ourselves on the detail of the finished product as this is what sets us apart from the other ‘run of the mill’ builders.


Our TV Testimonial

In September 2010, Redwood Construction owner Steve was asked to work as part of a team on the third series of Channel 5’s Cowboy Builders with Melinda Messenger and Dom Littlewood.

Steve worked on two contracts in Camberley and Ormskirk, having been brought in for his expertise in loft conversions and home extensions. The objective was to rectify jobs in which unscrupulous ‘cowboy’ builders had swindled customers, providing substandard work and leaving the jobs unfinished.

Steven finished both jobs of as part of a team, working to the strictest deadlines on the show’s 2 week timeframe for each job. The work was completed to the highest standards, putting a smile back on the customers’ faces and restoring some faith in the building industry.

All work fully estimated and guaranteed

All our doors and windows are fully guaranteed, from failed units to faulty handles, which means there is no small print – everything is covered.

Our UPVC window replacements meet current Building Regulation standards that require all windows to be double glazed energy efficient, reducing the amount of heat lost from your home, therefore decreasing your heating bills.

If you choose Redwood Construction, Manchester, you can guarantee you are getting the very best UPVC window replacements, as well as great customer service and a hardworking team.
