As you walk through your lighted rooms (preferably day light) see if the new coat has light spots showing the precious paint. This is call "bleeding through". This means that there's only one coat of paint or the paint was diluted or the trasition of colors were from light to dark (or the other way around) and primer was not use or the painter is inexperienced.
We used FHP to paint the interior of our home and were very satisfied with their work. Joe, the owner, was always available to answer any questions I had. He put up samples for us in each room so we could choose the best color. They prepped the house well and the end product was more than expected! His price was fair compared to competitors. FHP finished the project in a timely manner . He even offered to come back and touch up the paint after we have moved in ! I would recommend FHP for any job!
If your home was built before 1978, there is a good chance that lead paint was used in its construction. Scraping, sanding, or removing old paint can release toxic lead dust which can cause serious illness in children and pregnant women. Special handling is required when working with lead-based paints. If lead paint is present in your home, you will need to hire a lead-certified painting contractor or lead abatement contractor. Before getting started with your exterior painting project, consult your local building authority or visit www.epa.gov for more information.
We had a bad experience with an interior painter years ago, with the crux of the problem being him overcharging us at the end for "extra work" he didn't anticipate. One thing I'd strongly recommend is making sure it's in the contract that any additional work or growth work is estimated and communicated to the owner as soon as it is identified, otherwise the owner is not liable to pay it at the end.
Oh, where to begin? Let me start with 'watered down paint'. 25-50% before the material gets to the site? Impossible. You would basically be painting with water at that point. It would be less of a hassle, and cost, to simply use proper material. You would be forced to apply three coats instead of two, as the coverage would be horrible. Whatever cost you think might be saved in materials would be lost in labor.
I did go with the highest bidder and it did not matter. They did a shoddy job and threatened to take me to court when I pointed out mistakes that they made based on their work standards stated on the quote. I have not paid them yet, just filed a complaint with the BBB. No money down asked, no contract signed. The boss stated I have to high of expectations just because I live in a 121 year old house!
Never, never hire "Hanks painting" , he is a scam. He charged me 1800 for an 800 sqft house, with the agreement of painting the gutters. He not only didn't paint the gutters, the paint of the walls and front door is pealing off. He did not sand the door and the wall color is washing off. His people don't know the work and he much less than them since he painted the door.
