  • Replacement Window

    5.75Verified Review

    Replacement window. 95% of work was fine. However trying to get incorrect hinges replaced total joke. JML Window and Door Installations with excuses as to why they can't obtain hinges or find time to fit them. For a stress free life avoid at all costs.

    Nothing but delay after delay. Excuse after excuse. Took 4 visits by 2 different people over 7 weeks to replace a small window - and so much of my time wasted on calling and texting.

  • Brilliant service from start to finish

    10Verified Review

    This is the second time we have used Group JML, this time for a new front door. Service has been brilliant from start to finish. Jack gave great advice and took time to help us choose the right front door for us. The fitting process was stress free and efficient with everything left tidy. We also requested a change of handle which was done a couple of weeks after and when our fitter came back to do this I asked him to adjust the door slightly as we were finding it a bit stiff which he did with no problem at all and it’s now absolutely perfect. Thank you Group JML!

  • Terrible after sales service if issues.

    5.25Verified Review

    The work itself was completed to a satisfactory standard. Problem came once we had an issue. One of the windows in the front door had a blown rubber seal in it. Raised it with the company end of March as 5 year guarantee on the door. It is now well into June and still not fixed. Have called several times, sometimes get a answer machine, other times, excuses and that it will be followed up. I'm the one always calling, no updates back from Group JML as to what is happening. Even now trying to find out if the window will be replaced this week or not. They are not answering at moment.
