Great company and service! Two friendly and knowledgable guys came in the morning and changed 11 windows within 1 day. Very professional, very nice job for a great price! I would never use any other company except them. Thank you!
The work was excellent. Clearly communicated costs and no surprises upon completion of the job. They came when they were scheduled and they worked very hard and efficiently. They kept my house clean and were very courteous to my family and me. They were very knowledgeable and I’m confident recommending MHI to anyone.
