Contracting is not conducted very often. Or, is it? What about your internet or television provider? How about a restaurant? Are we not contracting a service? Other than hunger, the attraction of the food or the ambiance – ask yourself, what inspired enough interest for you to check that particular restaurant out? Maybe it was word of mouth, good reviews, a good sanitation score, a clean atmosphere, the professional service, the quality of the food, maybe being close by or locally sourced food also helped? While you were considering all these factors – little did you know – you were qualifying and researching before you chose to give that particular restaurant your business. Most dinners cost under $50 per person. Why wouldn’t we take the additional steps needed to qualify our potential contractors for projects that typically cost much more??
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.
I agree with JHs. If there is no new color on it at all, just talk to the painter about it, if it was an honest mistake (which can happen very easily while painting) your painter should have no problem fixing it. However, in my years of experience, it is not unusual for 2 coats of door paint (good quality) not to cover very well at all. I once painted a red door 7 times, plus a tinted prime coat before I found the door to be a solid color.
Unless you like textured walls, don't paint over dust. Wash the walls with trisodium phosphate (TSP) or a mild cleaner, like Jasco's TSP No-Rinse Substitute. For smoke-stained walls, Toto uses a 50/50 solution of bleach and water. To clean a wall, use two buckets. Load up your rag or sponge from your cleaning-solution bucket, and scrub. Before redipping, rinse the sponge in a second bucket filled with clean water.
Thanks, all, for your time & efforts adding to the article & comments, especially Dave urging requesting both General Liability AND Worker Compensation insurance certificates to protect from real & fraudulent liability--from my experience especially in California, where insurance fraud is a popular income thief, even causing car collisions to collect.
