Home Improvements

All types of home improvements carried out efficiently and in a timely manner. Contact John to discuss your requirements.


Kitchens renovated, from small installations and repairs to complete refits to the highest standard.


Extend your home rather than move. If you need additional living space then why not consider creating an extension rather than moving house. We can take care of every stage of the development. Give us a call to discuss.

Garage Conversions

Why not convert your existing garage into a useful living space? This is a cost effective way to add value to your home without breaking the bank. A garage conversion is far cheaper than building a brand new extension to your property and can be completed in a fraction of the time.

Conservatory Roof Conversions

Make your conservatory an all year round room and add value to your property with a Conservatory Roof Conversion carried out by a Penicuik tradesman, from planning through to completion.
The roof of your conservatory will be covered with a lightweight synthetic tile making for a warmer winter and a cooler summer.

Replacement Windows

With decades of experience we can efficiently replace your windows to help maintain the look of your home. With new double or triple glazed windows you will notice a difference in how quickly a room warms up and retains the heat. We can replace a single window unit or update all windows in your home, conservatory or extension.


We can fit replacement doors to your specification. A new door not only improves the look of your home, but due to better insulation can save you money on heating bills.


Large or Small, we can install or repair conservatories to the highest standard.
