"WOW.
I thought my 30 year old redwood deck wasn't salvageable, but Rupert convinced me to do so.  He was very prompt & reliable & knowledgeable and everything went as planned.    A real pleasure to work with, especially if you prefer texting over e-mails!!
I thought it was going to need replacement, a cost of $20,000 using a wood/plastic composite.  I am glad I didn't spend all that money- I would have had a plastic deck (Trex )that would scratch/warp/stain/turn to plastic-dust ( according to reviews at http://www.consumeraffairs.com/homeowners/trex_composite_decking.html) 
Instead, I have a sturdy splinter free redwood deck and $18,000 still in my pocket.  Environmentally I saved as well, by 'fixing & reusing rather than buying/manufacturing plastics that would end up un-decomposed in a landfill one day.
If you want a facelift on your old deck- Summit Deck Doctors is the way to go.
If you think your deck is dying and needs to be buried & replaced, don't do so without asking Summit Deck Doctors to resuscitate it.

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"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.

"DJ's recommended a color scheme and painted the exterior of our house. They weren't the lowest or highest quote, but they did an excellent job, went out of their way to please, great/friendly/nice crew and I would highly recommend them. They also spent a lot of time on the prep work on a 30 year old stucco house."

FAQs for deck, fence, patio or porch clean and seal projects in Mount-hermon, CA

You should clean your deck before sealing it. Cleaning before refinishing is critical. If you don’t remove dirt and debris, you'll trap moisture in the wood, which prevents the new sealer from working correctly and can lead to costly repairs. Whether you need to sand, power wash, or sandblast depends on your deck's condition.

Sealing and staining your deck are essential maintenance methods that protect and beautify your outdoor space. Stain adds rich color and guards against fading, while sealant fortifies the wood against moisture and weather damage. Wood type, climate, deck age, and the degree of existing damage determine whether your deck benefits from one or both treatments. Using both options extends your deck’s durability and enhances its overall appearance.

Power washing and sealing your deck costs $500 to $1,700. This process combines the removal of stubborn dirt and debris with a protective seal that preserves the wood’s integrity. Effective cleaning eliminates harmful buildup, and a proper seal prevents moisture damage and wood decay, ensuring long-term durability and reducing future repair expenses.

Your deck must be sealed every one to three years to maintain its strength and appearance. Regular sealing is essential to protect the wood against moisture, mold, and harmful UV rays. A consistent sealing schedule prevents rapid deterioration and costly repairs. Inspections should be performed annually to determine if the protective layer remains intact, extending the life of your deck.

Leaving your deck untreated compromises its structural integrity and safety. An unprotected deck rots quickly due to moisture and environmental exposure, which means that neglecting sealing results in rapid decay and expensive replacement costs of $4,125 to $11,650. Sealing your deck is essential for maintaining its durability and protecting your home.

The sealant on your deck dries within a few hours and reaches full cure within 72 hours before regular use. It is essential to wait until the complete curing period to ensure the protective layer fully sets and resists weather and foot traffic. Proper drying guarantees that your deck is fully protected against moisture and environmental damage, ensuring lasting quality.
