"Price quote was much lower than others, reviews from others very good, and BBB check showed he is BBB member with no complaints. Work was performed on time, included jackhammering out old skimmer from pool deck, installation of new skimmer, patch concrete, cleanup and rebalance pool water. Very pleased with the results."

"I had Paramount come out to give me an estimate on refurbishing my empty swimming pool. It had been leaking water and we emptied it 2 years ago so it was time to either fix it or fill it in.

The estimator/sales guy came exactly on time, discussed the process and the issues he could see and emailed me an estimate later in the day. The only fly in the ointment for this part of the process is that I wrote back and asked him what kind of things typically drove up the price of this type of project (originally slated to be a re-tile and re-plaster job) and he didn't have any. I think he could have but more on that later.

The workers showed up exactly when scheduled and got right to work. They found that much of the plaster had lifted away from the gunnite and they really had to take it all down. They also found about 3 times as many structural cracks as estimated but that had been left open so that was okay. I was disappointed to be hit with the new charge of stripping the pool but Jorge cut me a really generous deal for the cost of the stripping and the extra cracks and I'm pretty sure I got the better end of the bargain. They also found that there were cracks in the corners of the pool and they applied extra rebar and concrete to those areas. They did not charge me more money for those repairs.

The job started on 7/20 and by 7/29 water was flowing into the pool again and it looks great. The crew did a good job of cleaning up and I'm quite pleased with the outcome. I recommend Paramount without hesitation."

"I was recommended to Fine Point Painting by my parents. In the past my parents had bad luck with contractors who gave meaning to the term, Jack of All Trades Master at None. I grew up doubting contractors but Bill and his crew were fantastic. When he came out to do the bid he answered all of my questions and was thorough on explaining to me the reasons. When I had additional questions/concerns he was quick to reply via email.
The house we purchased to put it nicely, was in bad shape. Previously, it was a rental which I'm sure you can imagine the state
it was in. It also had termite damage in which Bill advised me to have the paint job done after the fumigation tenting. Apparently,
fumigation causes fresh paint to peel!!! Thank goodness we painted after the tenting.
We had the whole works done on the interior. The acoustic popcorn on the ceiling was removed, sanded, textured, primed, and
painted throughout the house. Also, the trim, doors and cabinets had oil based paint which needed to be sanded and primed in order for the latex paint to stick. The walls were sanded as well to remove embedded hair follicles and pebbles that were painted in the walls from the previous painter. Most of the interior of the house and entire garage smelled of animal urine and they pressure washed the garage with a cleaning solution to eliminate the smell. There were numerous cracks on the walls and ceilings which they filled. There were also 8 giant holes in the walls that they patched. They did an amazing job on the patchwork since you can't tell they were there!!! His crew was professional, courteous and they came on time. Also, they cleaned up after themselves very well. And this is coming from someone who is borderline OCD.
There were no hidden fees or added fees tacked on at the end. What made it easier for us was a payment plan which was broken down into 3 payment installations. This meant we paid them after each chunk of work was completed. I have heard stories where people have paid contractors upfront and the contractors run away with money or they don't finish the project.
If Angie's List had +'s and -'s I would give them A+'s. There are no words to express how pleased we are with Fine Point Painting. Our house looks amazing, the garage has no smell and I will hire them again for future projects.

"Pablo and co. are the best! When we moved we inherited a pool + service. However the service person wasn't so forthcoming when we asked questions. Enter Pablo. He came to our place, inspected our pool and told us everything about it. He answered every bit of questions we had and, get this, he wasn't a pushy salesperson! He even told us the prices of the chemicals he used to keep our pool sparking clean! (And that's why he charged what he charged us). Since then Pablo has expanded his business into designing/building pools. In fact we were so comfortable with him that we always thought of him if there's any backyard structure we wanted to add (such as the upcoming poolside shower). Give him a try, you wouldn't find anyone as honest and hardworking as he is. Worth. Every. Penny!"

"Vince and his crew were wonderful ? friendly, professional, effective, efficient, and all at a very reasonable rate. Two huge trees were
heavily trimmed and shaped, one smaller tree reduced and reshaped, two very large hedges and assorted shrubs trimmed.  I plan on having Vince do an annual maintenance from now on.

FAQs for swimming pool heaters installation and replacement projects in Morgan Hill, CA

Yes, you can add a heater to an existing pool. A pro can retrofit a heater to nearly any in-ground or above-ground pool. Adding a heater allows you to start the swim season earlier, finish it later, and maintain a steady water temperature in between. Many owners schedule the job during a larger pool upgrade, but it also works as a standalone project. Professional installation ties the new unit into the existing pump and plumbing for safe, efficient operation.

Most owners switch the heater on a day or two before they plan to swim, then shut it down afterward. Reaching the target temperature can take 24 to 72 hours, depending on pool size and outdoor conditions. Using a cover while the heater is off helps hold the heat and keeps energy costs in check.

Pool heaters can freeze if left exposed to extreme conditions. Freezing can damage internal heater components, potentially leading to costly pool repairs. Cycling water, covering the heater, and regular maintenance help prevent freezing. Sealing or winterizing your heater also protects it during the season—this involves draining water from the heater and its components.

Pool heaters operate with lifespans spanning from seven to 30 years. Gas and propane models last seven to 12 years, while electric and solar heaters perform efficiently for up to 30 years. Consistent professional maintenance and routine inspections extend the heater’s life and improve its performance, ensuring a safe and reliable heating system for your pool.

Before hiring a pool heater installation contractor, conduct thorough research by reviewing online feedback and gathering recommendations from trusted sources. Contact multiple professionals to discuss pricing, request references, and understand the complete installation process. This careful evaluation ensures you select a qualified contractor who delivers high-quality service and a successful installation.
