I would never suggest that one of my clients buy their own paint because A . They will pay an average of $20 to $30 more per gallon which could add up to $1,000 or more to a full repaint B. most times I'm in the paint store homeowners are kind of pushed to the foreground as they handle all the contractors in the store and C. Paint is heavy, takes up a lot of room needs to be left in it clean dry area and I hate to put a client to work when they are trying to hire me to do their job.
A thorough scrubbing is a must before painting any exterior surface. It removes the dirt and broken-down paint residues that keep fresh coats from adhering and gets rid of mildew that grows on paint in all but the most arid climates. Most contractors clean with pressure washers, but in the hands of someone unfamiliar with the equipment, these can gouge wood, shatter glass, and drive water behind siding and trim. Using a hose, a pump sprayer, and a scrub brush is slower but safer, and just as effective.
Being in the business for 25+ years I have had the privilege of working with thousands of clients. Although they all came from different circumstances and backgrounds they all had one common goal in mind. Every one of them wanted to be respected, receive top value for their money, and get the best possible paint job for their most prized possession, their house!
Ours was a big job. We chose to work with three colors, one of which Sang and his partner painstakingly applied to all our window trim and grids. But before the colors came the preparation. The detail and precision of their work can not be understated. Even the taping of plastic was performed with purpose, each edge a clean line. Sang inspected all phases (patching, sanding, and power washing) with great attention and after three days of intensive work, it was time for primer and paint. Sang is knowledgeable and gave us great advice on how to best use our colors. Again, he payed close attention to detail, making sure that our house looked beautiful. We are extremely pleased!
When I had my interior painting done, after clearing out all of the furniture, myself, I also removed all of the wall plates in all the rooms to be painted. They were a beige color and probably yellowed. The wall was originally an off white and I had it painted a light-mid grey, so those wall plates would look terrible. After pricing replacement plates, switches and outlets (Would have been way too expensive to replace all of them), I decided to just paint all of the wall plates, switches and outlets (Used just a black gloss spray paint). I sprayed the plates outside and used a small brush on the switches and outlets. It worked out just fine and the blacks plates, etc compliment the wall color. It has been 7 years and the plates, switches, outlets are holding up well.
Paint gets more expensive as you go from flat to gloss. The difference is usually around $1 per gallon per sheen upgrade. Flat is the cheapest, then matte flat or eggshell, satin, semigloss then gloss. Paint also gets much more expensive the darker it gets. A white or neutral paint color can be as much as $20 less expensive than a deep base red or blue.
If the point of hiring a well established, experienced, reputable painting contractor is to secure the professionalism and trust suggested to be inherent with that choice, then I would EXPECT that professionalism and experience to include the ability to make the proper and correct calculations for labor and materials for a fixed price quote, and there should be NO reason for the contractor to put the cost burden of their miscalculation on the consumer.
Painting contractors must also carry out administrative and marketing duties. They prepare final accounts for customers based on the original estimates and any additional work. They analyze the cost of the job compared with the estimate to calculate their profit. They market their business through activities such as setting up websites, asking customers for references or contacting property maintenance companies with details of their services.
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.
My husband has been a professional painter over 30 years. He prides himself in his high level of work ethic and customer satisfaction. He stays up to date on techniques and finishes. He gives Very detail and accurate appraisals with contracts. At an alarming rate, as he starts to finish the last day or the day before, the client starts nit picking and being disrespectful towards his work when every day prior to that, they were very pleased, as he request ongoing satisfaction throughout the job. Then they don't to want pay remaining balance, bicker about final cost, or stop payment. He has a crew he has to pay whether the customer does or doesn't honor the contract as well as our own household expenses. Wasted time ,labor, money and effort lost. Now how do we fix this? Remind yourself and clients that a contract is based on honor.
