Silicone Rendering

Dale has been a star. From his first visit to give me a price, to completion of the works. Punctuality and communication of the Greenoak team (Dave/Ray/Callum) was excellent.I am so pleased with the job that Greenoak have completed for me. They were professional, tidy and worked so hard. The job is finished to a high standard and I will 100% use them again. Would highly recommend.

We wanted to replace all of our windows - we conducted our due diligence and of three companies Greenoak were not the cheapest but we had no hesitation in giving them them the work for their overall service - from the time we had Glenn quote, to visiting the showroom, communication from Dione and Stuart and Ed whose installation quality and attention to detail was superb and after service when we has snagging issues nothing was a problem for any of the team. We have had many of our neighbours compliment the windows. If anyone is looking for windows, doors this is the company to seriously consider.

Amazing work carried out by the guys at Greenoak

Amazing work carried out by the guys at Greenoak on the applying of the silicone render to the front of our house. First I would like to say that there was no pushy salesman. A major plus in my view. From the initial conversation with Dale, to the rendering carried out by Dave, Callum and Ray, everything was proffessional and considerate. They made, what can often be a very stressful experience (with having strangers work on your home), very easy and reassuring. The end result looks amazing. I'd also just like to mention the scaffolding company that Dale uses. I've never known one that is so professional. They knew what work was being carried out, but still discussed the erecting of the scaffolding to ensure we were happy with their work. Before then all scaffolders I'd experienced simply turned up, threw up the scaffold and disappeared without confirming if there were an issues with what they'd done. This team was a breath of fresh air.

Top notch company

Top notch company, top notch service, top class fitters, all round pleasant experience. However, we did have an issue with the Rock Door as made by Gap plastics. Sadly I cannot sing the same praise on Gap! But Dale did his level best to sort it and eventually we got a replacement. Shame on you Gap!

A very competitive price for an excellent job. The patio doors were fitted efficiently and with minimal disruption. The fitters were polite and the doors were fitted within a few hours. Would certainly recommend Greenoak especially for their honesty when I overpaid!

Replacement conservatory roof

Fantastic job. Everyone was professional and friendly. Every aspect of the job was explained very well and the work was undertaken according to the timescales given. The quality of the materials and the fitting along with the finish was of a very high standard. All professionals were meticulous and very tidy. Would highly recommend Greenoak.

Greenoaks look after you.

Greenoaks look after their customers in that they put concerns raised by the customer to the trades who carry out the work. This is reassuring because tradesmen can be intimidating so don’t have to worry about raising issues you want correcting.For instance the rendering primer is a messy process and some splashes and runs went on to unmasked areas. This was remedied after raising the matter with Greenoaks. We are returning customers and are pleased with the quality of the silicon rendering work they carried out. They replaced the rain water down pipe as it enhances the overall finish.

New roof on conservatroy

I am extremely pleased with my new conservatory roof installed by Greenoak. The company was very professional, from the initial consultation through to the installation and communication was great. The fitting team, plasterer and electrician were brilliant and I knew exactly who was coming and when they would be there. I now have a room I can use all year round. I would definitely recommend Greenoak.

So far very happy with the installation . Our tired old conservatory has been totally transformed by the team at Greenoaks. They worked cleanly and efficiently whilst navigating our day today running if the house. We’re actually looking forward to the heat of summer and cold of winter!!

Dale, you and your team, thank you so much for your time and dedication. Our new composite Rock door looks and feels fantastic. It feels really good using a local company that cares about their customer from start to finish. Thank you

We have had a solid roof put on our conservatory by Green Oak. We were very impressed from the outset. Dale took time to explain every aspect of the build bringing a model of the roof so we could see the construction. Then he left us think about it and there was no hard sell. The workmen were very pleasant, friendly and worked extremely hard. Despite being one man down the other chap worked late into the evening to make sure the construction was finished on time ( rather than have to come back for a couple of hours the following day), as did the man doing the plaster boarding. Every evening the site was left tidy and all rubbish taken away once the work was finished. The plasterer and electrician also did a brilliant job and all works was finished on time. We are really happy with the end result and couldn’t recommend the firm more highly. John & Rita Dobinson

We needed 11 new windows of various sizes so we spent some time searching reviews for a highly rated but local Double Glazing window installer. Greenoak came out top of our search results, We reached out and Dale responded quickly followed by a visit a few days after. The resultant quote was very competitive versus other quotes we had received. It was an easy decision to go with Greenoak. Dale came across as very knowledgeable, friendly and genuinely customer focussed. He invited us to the showroom in Leigh where he took us through the detail to ensure we were fully aligned on requirements and expectations. We were very impressed with him and his business and by his overall professionalism. The installation took place on 20th Feb 2023 and took 4 days in total. The whole process was exemplary, we could not fault the team in any way. They were tidy, considerate and very thorough. We have had windows fitted before by various other company's but the quality of fit and finish from the Greenoak fitters was far superior. The guys worked solidly and clearly did not skimp on anything, ensuring that the windows were not only properly fitted but sealed professionally too. They did an outstanding job including clearing all of the old windows and rubbish Overall we'd rate Greenoak at 10/10. We felt reassured by their high standards of work ethics, integrity and customer satisfaction. We honestly doubt there is anyone better out there for this type of work. We therefore wholeheartedly recommend them Ian and Jenny

Fantastic job done by Greenoak, the guys were professional, friendly and a pleasure to have in my home. I couldn’t be happier with the job they did. Highly recommended.

Brilliant company, very friendly and easy to work with. Very pleased with the finished cladding on our office wall - excellent quality and good value

Replacement Conservatory Roof. Fantastic company and service from the whole team! Dale is great and gave me a quote for my new lightweight roof, great bloke and not pushy, loved the fact he gave a all in price rather than start low and add extras. The fitting team are fantastic!, Mike, Mark and Casper treated my home like their own, , great attention to detail and did everything I asked to get the perfect finish, I honestly cant find 1 fault and I am fussy! I could not be more happier with my roof!! Take my advice, Don't look anywhere else ,I cant rate them highly enough. Greenoak are the BEST!

Following our initial discussions with Dale, our expectations were already set high when it came around to installation. Some truly awful weather right at the start of the installation virtually wiped out the first two days work, and the anticipated seven day build seemed to be in jeopardy right from the start. But Mike and his crew - supplemented by two and sometimes three others, working in still inclement weather, brought the build back on schedule by the end of day five, and the plastering and electrical second fix over days six and seven meant the whole project was delivered to time, and budget meaning that our initial high expectations had even been exceeded. I have nothing but the highest regard for their workmanship and scheduling - and not forgetting Dione in the office who kept me informed throughout and efficiently managed the stage payments. In my experience it is unusual to receive a great sales pitch and then to have that exceeded by the installation teams - I couldn't recommend Greenoak's services more highly.
