Fix water leak under front door

Interior Waterproofing Newlands, Wellington

Issac assessed the issue thoroughly and explained clearly what needed to be done. He carried out the repair, resealing the area properly and making sure everything was watertight. We have since checked the door during rainfall and no water is coming through anymore. Issac’s communication was excellent throughout the whole process and he was friendly, efficient, and easy to deal with. I’m very happy with the quality of his work and would highly recommend him to anyone needing general maintenance.

Mike did an excellent job on a difficult piece of work. From understanding the problem, providing a good solution, working in the freezing rain, digging out clay and then remediating the pavers and the drain to a high standard. Very happy that he could help us out. Could not have done it myself, even if I knew how to.

I found Zac , owner/operator of Exhibit Insulation , enthusiastic as he answered the posting quickly and proved to be reliable, courteous, punctual , with prompt/ detailed communication, and very good workmanship . Overall the cost of the job was reasonable . That the work was not able to be completed at one time was not his fault. I would certainly recommend Exhibit Insulation and would use him again .

Craig's communication was excellent from start to finish. He regularly provided updates on the status of the job and presented me with all the details and options so I could make an informed decision. The quote was accompanied by a detailed description of the work to be carried out. The builder was a very hard worker - arrived on time, worked hard and always cleaned up before he left for the day. It was a great experience from start to finish. Highly recommend Craig and his team.

Membrane Waterproofing Avondale, Auckland

5.0

Danny does exactly what he says he will do. He is excellent at identifying practical problems. I had a further issue after he had done the job and he willingly came back to look at the problem. The problem had nothing to do wiry his own work but was a roofing problem which he identified for me coming all the way to my house on a Saturday morning. In addition Danny has excellent manners! Incredibly polite and respectful.. his communication is excellent and very responsive.
