Professional painting services. On my exterior paint jobs we pressure wash, caulk ALL seams as needed, prime entire siding and trim using an oil based primer, spray 100% Acrylic latex paint to siding and apply by brush/ roller to all trim. Alot of people ask me why do I prime the whole house? Many of the paint manufactures state in their warranty that the house must be primed to recieve warranty. 99% of the paint stores will also tell you to prime with oil for a better, longer lasting paint job. Why dont most guys do it? Its more work for minimal gain on their part. The cost to you is minimal. I treat your home like it was my own. References upon request. For the best bang for your buck and a paint job that will last as long as the product used says it should, send me an email. It doesnt cost you anything to get a bid, it only cost you extra when you have to paint again in 5 years.
