“My bathroom floor looks like a piece of art. I highly recommend!!”

New Castle County / Since 2006
Measured craft, entire homes. One accountable team for the kitchen, the roof, the addition and everything that connects them.
One house. One standard.
Luxury lives in the joins. The line where a new room meets the old house. The moment the cabinet, floor and light finally agree. Delpa brings every trade back to one clear plan.

Before you call
Delpa works from New Castle, Delaware, and takes residential projects throughout New Castle County — including North Wilmington, Newark, Bear, Middletown, Hockessin, Claymont, Glasgow and Pike Creek — plus southern Chester County, Pennsylvania, around Landenberg and West Chester, and into northern Maryland. If you are not sure whether your home falls inside the service area, call 302-731-7302 and ask.
Yes. The first visit is a practical look at the space, the scope and what is realistic. There is no charge and no obligation to proceed. It ends with a clear picture of what the work involves rather than a pressure pitch.
Delpa Builders LLC is licensed, bonded and insured for residential work in Delaware, and carries insurance for the work performed. Licence and insurance documentation is available on request before a contract is signed.
That is the point of the way Delpa is set up. Interior, exterior, expanded living and new construction all run under the same team, so the kitchen is planned alongside the wall it opens into and new windows are considered as part of the whole exterior. It removes the gaps where projects usually go wrong.
Price depends on scope, structural change and material selections, so there is no honest flat number. What Delpa commits to is a complete quote: the initial number is built to cover the agreed work rather than starting low and growing through change orders. Materials are bought directly from manufacturers where possible to keep budget in the work itself.
Delpa maintains a standing 5% senior discount on qualifying projects. Ask about it during the consultation.
Yes. Call 302-731-7302 directly for urgent roofing and storm-related needs rather than using the contact form, which is checked less often.
