What can I say that could convey how great Oaktree are! We bought a staircase about 28 years ago which looks as good today as when it was first installed. 4 years ago we commissioned some awkward sized doors and windows which we have been delighted with. However, over the last weekend the lock failed to work, today I called Oaktree to see whether it could be fixed, and guess what, within hours they came to the property, changed the gearing mechanism in the lock and it now works perfectly at absolutely no charge as it was still covered by the warranty. I am so impressed, what service!! Thank you so much Kevin.
