"Neil Umphress explained exactly how he would complete the installation of insulation in my attic including the type of material he would use. When a problem was encountered he discussed how it could be handled and left the decision to me. They worked all day with a lunch break Then another problem occurred and I thought they wouldn’t be able to finish in a day, but they pushed through, cleaned up and even insulated an area that was not in the contract just because it needed it. I have more work and will definitely call Neil Umphress to do it. "

Dock Building and Repair questions, answered by experts

If your boat dock and seawall appear to be failing at the same time, taking on the projects together may be easier from a permitting perspective. By doing a big project, you can ensure that everything in your property is safe and up to code. Depending on the size and condition of your boat dock, average boat dock repair cost can range from $834 to $5,432.

Repair costs range from $500 to $5,000, depending on material type, structural damage, and labor. Extensive piling or decking replacements increase the price.

Docks can last between 20 and 30 years, provided regular maintenance has been performed. Upkeep tasks like staining your dock annually to prevent water damage, repairing broken elements quickly, and using dock covers regularly will help extend your dock’s life. Your dock is likely nearing the end of its lifespan when it shows signs of rot, rust, and foundation damage.

Most dock repairs take 1-5 days, depending on the extent of the damage and weather conditions affecting the work schedule.

Minor repairs like replacing boards can be DIY-friendly, but structural or underwater repairs require professional expertise.
