Attic Removal

Assisted Review

An assisted review is collected by a contractor on behalf of the homeowner after their work is completed. The homeowner must confirm the text of the review and may make any changes she or he deems appropriate. The homeowner then assigns the contractor a review score out of 10. Assisted reviews receive the same scrutiny as other reviews and must follow our review guidelines.

The sales person (Alana) was very helpful. Our experience with the crew was excellent. They were very polite and attentive to detail. They kept our house as clean as they could considering their task. If I were to have one negative comment it had to do with the scheduling. We were advised two weeks in advance the crew would arrive in the AM of the 24th between 8:00 AM and 9:30 AM. That time passed without phone call. I followed up with your office in Milton and was told that I would receive a return phone within 1 hour. That time came and went. We were now worried that the entire job was not going to happen. We called again and this time it was confirmed the crew would come in the PM. Suggestion: Give a pre date confirmation of the job. The times could be reconfirmed and it would also alleviate any confusion on the part of the customer.

We are enjoying the comfort of the new attic insulation.

All staff involved were excellent! We first dealt with Ian who provided a quote back in May and responded back quickly when we had to modify the quote slightly. He was very courteous, professional, thorough and actually crawled in the tight attic in order to visually see what insulation was required.

Kelly and Mandy scheduling the work were very pleasant and accommodating.

Kudos to GNI and their staff.

I would like to commend the two installers, Cory and Adam I believe, for their professionalism and the pride they both took in their work. Despite having some challenging areas to work in and moving between finished and unfinished portions of my home, they kept a quite clean work space and left very little behind to tell they were there. They both took into consideration where equipment was laid and how it may damage existing walls and trim and protected those areas appropriately. The only criticism I have of the experience was some over spray on a small portion of floor which likely was just missed during cleanup and I was able to easily remove it with no issues.

I would be happy to provide a great reference for these two individuals work in the future and it has been my second good experience with GNI. I look forward to doing business with you again in the future of I require these services again.

This is to express my great appreciation in your team and professionalism. After receiving the quotation and prompt response to meet our family needs your team have demonstrated true customer appreciation. They have gone the extra mile to help me empty the garage when I had not done this the day before. The willingness to even to lend a hand that was not detailed in their scope tells me that they care about their customers.

GNI, will be recommended amongst my future communication.

The installers were were great positive people. They were polite and you would never know that there was a mess as it was all cleaned up. Even though the machine kept breaking down, they were apologetic and needed to borrow some of my tools to fix the ongoing problem. It stills leaves a positive experience in my mind and I understand that things break down and was not the installers fault.

As for Alanna , I was impressed by her and that is why I went with Great Northern for her professional attitude.

I will recommend you to others if I hear of any others are looking for your services
