Grammar Electrical responded quickly and found the faults that were causing the electrical problems to the property. The office people were very efficient and kept me in touch with details of the work done. I recommend this firm highly for courteous attention, arriving on time and sorting out several problems at once. I would recommend them as an Excellent firm.

When disaster strikes it's great to know there are trusted professionals around to sort out the problem - Grammar Electrical promptly found out the RCD was being tripped by a faulty washing machine.
They responded quickly and even though it was a Sunday evening their excellent electrician arrived to trouble shoot and restore our power and Internet. I can't fault (pun intended) Grammar Electrical and give them my highest recommendation.

My gas water heater was not working last night. I contacted their customer service today and their service was fast and great. At the time when they arrived at my house I was not home. They went to my back yard to do testing on my gas water heater and brought me with a good news that the unit was working OK. To prevent no hot water again, they even taught me how to do testing. Thanks for their great service.

Excellent service. The electrician was helpful in his explanations and did a great job with extra work dealing with an older house.

Great quote with a comprehensive plan to complete the job.  Matt listened to what I (the client) wanted and explained what was needed to get building consent.

I call Grammar Electrical for all our household needs! They upgraded our old 70's switchboard with beautifully labeled new modern and safe unit, hard wired our spa pool, and are always on hand with quick and efficient service should something go wrong. They are great communicators for bookings and the technicians on the ground have great house manner and are punctual. Highly recommended.

Fantastic service. We had flickering lights with reduced power on a Sunday. Within 1 hour Grammar Electrical we’re here. So knowledgeable, they rectified previous shoddy work by another company and made everything safe. They are also returning to update internal box because of the age of our house. Great explanation of what the problems were. Highly recommend.

I strongly recommend Water Works for their professional and efficient service. We engaged Water Works to identify our roof leakage issue, Zane from Water Works provided a thorough check and identified the issue quickly. Leakage problem has been attended to efficiently. Happy to recommend to all my friends :)

We needed to get an Electrician to sort out a connection issue that was preventing the use of one of our machines. Prompt response and Deon was quick to identify the problem and fix it.

Emergency HWC replacement. Guys were really communicative and worked super hard and late as everything went wrong - cylinder assembled wrong at factory and leaked, really bad weather limited roof access, parts by factory supplied were wrong - you name it. But they pulled finger and got it done - thx so much!
