  Despite the home being delivered ahead of schedule, multiple deficiencies have created significant financial and physical hardship, undermining the integrity of the builder's process and the condition of the property.
  I purchased the home in 2023, expecting completion and closing in March or April 2024. The builder unexpectedly accelerated construction, forcing me to vacate my rented apartment early and incur over $2,000 in relocation costs. Nearly one month after the home's premature completion, I was charged over $200 per day in penalties for delayed closing, even though the home remained incomplete and improperly finished. Closing occurred on February 7, 2024. Outstanding Construction & Safety Issues
  - HVAC Deficiencies - The master bathroom was delivered without any HVAC ventilation.
  - A vent was later cut into the toilet area, but no ductwork was installed, and airflow remains inadequate. - The master bedroom has only one vent, despite its size requiring two. This was verbally confirmed by a site inspector, but no corrective action has followed.
  - Multiple inquiries regarding the expected air supply and ductwork have gone unanswered.
  - Electrical Code Violations - The master bathroom lacks required GFI outlets above the sink, posing a direct safety hazard and violating building codes.
  - Drainage Issues
  - The walk-out basement floods regularly due to poor external drainage, causing water damage and safety concerns.
  Financial & Emotional Harm
  - The premature closing demand, combined with daily penalty fees, created an undue financial burden. - Extreme seasonal temperatures have caused physical discomfort and emotional distress for my household during Summer and Winter 2024, and now Summer 2025. - Despite multiple emails and verbal confirmations from site personnel, no repairs or follow-ups have been completed to date.

  We truly apologize for any frustration you have felt during
  this process. Our goal is always to provide a respectful, transparent, and
  supportive experience from contract to closing. We’d like to provide some additional
  context and address your concerns. We will follow up with you directly to
  discuss further.

  HVAC/GFCI Concerns
  

  When you first reported your HVAC concern in December 2024,
  10 months after you moved in, our team responded immediately. A Blenheim Service
  Manager was at your home the following morning, when we determined that a supply
  vent in your primary bathroom had been mistakenly covered during construction. A
  transfer grille above the door (to allow HVAC flow from the bathroom into the
  toilet room) had also been covered. We sincerely apologize for those errors, as
  our Service Manager expressed at that time. We corrected the issue with the bathroom
  ductwork promptly after our initial on-site visit.

  Our Service Manager followed up with an email, indicating
  that we would be more than happy to arrange for a New Castle County inspector
  to revisit your home to provide you with peace of mind regarding the work that
  had been done. This offer was declined.

  When our team arrived for the appointment you scheduled in
  March 2025 to install the final bathroom register and finish drywall repairs to
  close up the holes, you declined to allow us to perform the work. This refusal
  was documented in writing.

  Your primary bedroom vent was visible, fully functional and
  operating as designed. No additional vent is required based on the approved
  HVAC load calculations.

  It’s also important to note that modifications made to your
  home after closing without a permit – including removing a structural wall to
  create a closet and finishing your basement without HVAC load recalculations – directly
  affect system performance. These changes are outside of our responsibility and
  compromise the original design and function of your HVAC system.

  Regarding your mention of missing GFCI outlets: our team
  explained on December 12, 2024, that your bathrooms and kitchens are protected
  by GFCI breakers in the electrical panel. This design meets all applicable code
  requirements and was verified during inspections prior to settlement.

  ___________________________________

  Basement

  Your home does include a walk-out basement with an area
  drain at the bottom of the stairwell. The required maintenance of these drains,
  including keeping the drain cover free from leaves, grass, and debris, is
  something that is explained to every homeowner during the new home orientation.
  Failure to keep the drain clear can result in temporary water backup during
  heavy rains, which may lead to water breaching the basement threshold. Please
  also keep in mind when you finish a basement without permits, this always carries
  the potential to cause further issues. We can discuss this further when we reach out to you.

  ___________________________________

  Settlement Timing

  The Agreement of Sale you signed on 2/4/23 contained a
  tentative settlement date of 10/30/23. This was based upon you removing your Home
  Sale Contingency on 4/4/23. We granted extensions for your Home Sale Contingency
  Removal; you ultimately signed the Home Sale Contingency Removal on 6/16/23. That
  approximately 2.5-month delay in Home Sale Contingency Removal pushed your
  settlement date back approximately 2.5 months. These expectations on timing
  were set when you signed your Agreement of Sale and again when you signed your Home
  Sale Contingency Removal.

  We had accordingly planned for a 1/16/24 settlement (you
  received our standard notice of settlement date on 12/21/23). We pushed it back
  13 days (to 1/29/24) to allow ourselves time to attend to some final items in
  your home and provide you with additional time you needed for your mortgage process.
  Your home was completed, passed all required county inspections, and received
  its Certificate of Occupancy from New Castle County by that revised settlement
  date of 1/29/24.

  Unfortunately, we did not receive a "clear to
  close" from your lender by 1/29/24, despite the extra time allowed. As a
  result, per the terms outlined in your Agreement of Sale, a daily delay fee was
  applied for 5 days. This is a standard practice within residential real estate
  contracts.
  

  We understand how stressful the home-buying process can be,
  especially near the end, and we remain dedicated to supporting you through our
  post-settlement warranty program to address any warrantable concerns.

  We are committed to building high-quality homes and standing
  behind our work through our comprehensive warranty process. We will reach out
  to you directly to discuss these matters further and look forward to working with
  you to resolve any outstanding, warrantable issues.

  It will be 5yrs the end of this month that the issues we’ve had with our home has not been taken care of. To list a few we have electrical switch installed wrong, damaged singles, damaged siding, drip edges/flashing installed wrong, front porch that’s pitched towards the house, damaged trim, a lawn wasn’t graded correctly, that also has ankle breaking dips in it, bird cages that were not installed in the bathroom vents and we had on fan burn out due to a nest (FIRE HAZARD)…… ect. I have emails and text since the start showing the hardship and hassle they put us through to have what should have been right or at least fixed in a timely matter. They even called the police on me for showing up the main office to speak to whoever was in charge of this (PJ) (I called and left a voicemail with him today). They always have a reason for why these things aren’t done. The main reason I get is Covid and the contractors said they fixed it. I’ve sent pictures (2/3 separates times just this year) showing it’s not done and their representative (who’s nice) has come out 3x. Even he was shocked on the 3x that it was still not done. I can tell you 9/10 owners here will say they gave up on having them fix it. The state of Delaware of the BBB needs to step in and help. 5yrs is a bit much. Covid can’t be used for things that needed fixed outside of the house. So Blenhim reach out and let me know if you refuse to do what was agreed in our contract or you will have it done. Just a few pictures are provided. BBB please reach out so I can forward all emailed, text and pictures.
