General Handyman
Thank you Sergio for coming on such short notice and making yourself available! Sergio was able to fix a door hanging incorrectly, plumbing, bath spout, electrical and wall-mounted a TV in minutes! Very knowledgeable and professional. Thanks again!

Drywall & Painting
Sergio went beyond the call to fix a hole in the wall. He found the cause, fixed the hole, but also replaced the gutter, sealed all the cracks in the area and repainted everything to match. He also did some highly skilled drywall work (the ceiling has curved corners). I'm impressed and would definitely use him again.

Plumbing & Appliances
Sergio was really good and honest. He knew exactly what he was doing when replacing my garbage disposal and fixing one of my kitchen cabinets. I would recommend him to other people who need a good handyman.

Caulking & Sealing: FAQ

How much does caulking cost in LA?

Flat from $90 depending on linear feet and how much old caulk and mildew must be removed first.

Will it stop the mold coming back?

We remove the old caulk and mildew and use mold-resistant silicone, which holds up far better in wet areas.

Caulk or grout: what do I need?

Caulk seals where two surfaces meet (tub-to-tile); grout fills between tiles. See grout repair if it's the tile joints.

How long before I can use the shower?

Silicone usually needs ~24 hours to fully cure before getting wet.
