5***** Yell Review

Thank you Sally!!

There are few words which could express how impressed i have been with the penknight team, especially Kimberly, whom has moved heaven and earth to help us in our hour of need. We were left with a hole in the side of our kitchen, much sooner than expected, when a steel was installed to facilitate the installation of new patio doors. With four young children at home, this was a nightmare for us. However, Penknight saved the day by making and delivering the doors as quickly as they could, going above and beyond to help us. I would highly recommend this company.

The doors are perfect. Thank you. I am sorry for the delay in sending this email…  It doesn’t rain it pours…

Please do send me links to everywhere you would like a reference left as I would very much like to shout about how fabulous you guys are…
 thank you so so much. I cannot put into words how much your efforts mean to us as a family. You really are saving the day!
Bye for now,

Below are some of the emails we received.

Attached picture of our front door. Not the best picture but we completely love it. A long wait but it gives great pleasure every time we see it from inside or outside. Definitely worth waiting for and even better than hoped for
 Many, many thanks.
Happy New Year

Their team are just a pleasure to work with and we are so pleased with all the work you have done for us Best Wishes Sarah & Andrew.


Lovely comments on the sun room we completed at Charlestown

A simple idea brilliantly executed. Penknights team built the whole unit off site and fitted it without any alterations or complications. Not as easy as you would imagine, most oak companies would struggle with this type of work. Well done.....Dave.



Dear all at Penknight,


Just thought you might like to see your doors all fitted. I know we had a few problems along the way but now all fitted and forgotten.  We are extremely happy with them Thank you and Kind Regards Debra and Douglas Boddington.


Wow these look fantastic thank you so much for taking the time to share them with us!!


Dear Kimberley,
I have received the delivery, yesterday. 
I am very happy with the amazing quality of the windows and doors!
Kind regards

Hi, I have left a review on Yell and hope it worked??  just wanted to say that I found your website very intuitive and once I thought you may be able to help I rang and spoke to a very nice lady, who immediately put me at ease as my enquiry and request was not straightforward ( for me anyway) She talked me through the options available and gave great sound advice and once I ordered the door and frame I was kept informed of the delivery schedule. The two guys who delivered the door kept me updated via mobile ref delivery time and once they arrived they were great company, talking me through next steps and what to do to get the best out of the product. Next time I need a new door or window I shall be contacting Penknight Carpentry without hesitation. So nice to get great customer service like this nowadays!

The guys are here and the windows and doors look fabulous. A really welcome distraction for me today. Thank you. 

Speak soon and take care,
Best wishes,
