ThermoGreen - Your One-Stop

Home Improvement Shop 

Let us help you turn your home into a thermal efficient haven, cheaper to run and lovely to look at. 

Are you finding your conservatory too hot in the summer and too cold in the winter?  Would you like to consider insulating your conservatory roof so that you can use it 365 days of the year?  A thermal efficient insulated ceiling or a solid tiled roof will make all the difference and you will release the space your conservatory can give and extend your home without lifting a brick!  

Maybe your existing conservatory is a little dated and you fancy sprucing it up or renewing it completely.  It can become a much used and inviting living space expanding your home in an instant.  

Do you want to extend your living space, but don't fancy the prospect of the lengthy planning process and building an extension with all the mess and cost that that entails?  Talk to us about our 21st century conservatories - completely useable living spaces to be enjoyed all year round that are also energy price rise friendly with their insulated roofs and A-rated windows and doors.   

Do you want to achieve maximum thermal efficiency with new A-rated double or triple-glazed windows and doors in your home or your conservatory?  A good idea now with the price rises on our energy bills.  

Do you fancy a smart, energy efficient, super safe composite front door that offers a warm welcome to visitors?  You might simply have some misted up window units that need replacing.     

Whatever your home improvement requirement, pop in to see us in our showroom in Horncastle, or give us a call and we can arrange to visit you.  Totally non-pressurised with no obligation we will just give you good, sound advice and quote you a sensible price for an exceptional quality product.
