ThermoGreen - Your One-Stop

Home Improvement Shop 

Due to the latest Coronavirus restrictions, we have had to close our showroom to the public.  However, we are permitted to continue our work in all other aspects and are 'open for business'.  We take the health and safety of our customers and our staff extremely seriously and adhere to all Covid rules and advice.  

Give us a call for a friendly chat about your home improvement project now and beat the rush that post Covid will bring.  

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 you can use it 365 days of the year?  A thermal efficient insulated ceiling or a solid tiled roof will make all the difference.  

Do you want to achieve maximum thermal efficiency with new A-rated double or triple-glazed windows and doors?

Do you fancy a smart, energy efficient, super safe composite front door (and maybe even a new remote control garage door in a colour to match!)?

Maybe your conservatory is a little dated and you fancy sprucing it up or renewing it completely.

You might simply have some misted up window units that need replacing or some handles that no longer work efficiently.  Possibly, you might be considering a canopy over your front door to smarten the look of your home.    

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. 

Oh, and we also do blinds!  Treat your home to some pretty new blinds for your windows and doors – it’s amazing the difference it can make to a room just by changing the window drapery!

Here at ThermoGreen we don't believe in pressurised selling. From the moment you contact us we are friendly, knowledgable and helpful. If you would like us to visit you at home, we will simply turn up at an agreed day and time, show you the product you are interested in, answer any questions you may have, take approximate measurements where necessary and then either give you the price there and then or tell you that we will put your quotation in the post within the next couple of days.

It is entirely up to you when, or if, you come back to us. There is absolutely no hard sell.
